Potty Training Tips for Dads: The No-Nonsense Guide

Most potty training guides are written for mums. They assume you have been the primary caregiver for the last two years, that you know every tiny routine, and that you have infinite patience and a bathroom stocked with sticker reward charts. Great.

This one is for dads. It assumes you are competent, committed, and would like a straight answer on what actually works, without the condescension. So here it is.

Ignore the Age. Look for These Behaviours Instead

The "start at 2" guidance is a rough average, not a rule. Kids vary wildly. Some are ready at 18 months. Others are not ready until 3 or beyond. Starting too early does not speed things up. It just means more accidents over a longer period, more frustration for everyone, and a higher chance of your kid developing a negative association with the potty before they have the physical capacity to succeed.

What actually tells you a child is ready is behaviour, not a birthday:

• Staying dry for 1-2 hours at a stretch. The bladder has to be physically capable of holding it. If the nappy is wet every 20 minutes, the hardware is not there yet. This is a physiological prerequisite, not something you can rush.
• Hiding to poo. Classic one. If your kid disappears behind the sofa, goes quiet, and reappears looking suspicious, they know something is happening. That body awareness, the ability to sense an impending bowel movement and react to it, is exactly the foundation you need.
• Pulling at their nappy or telling you it is wet or dirty. Discomfort awareness. They are registering that something has happened and they do not like it. Good sign.
• Showing interest in the toilet or watching older kids and adults use it. Curiosity is the best motivator you will ever have. Do not discourage it. If they want to follow you into the bathroom, let them. It is modelling, and it works.
• Following simple two-step instructions. "Go get your shoes and bring them here." If they can do that, they can follow the potty routine. This tells you the cognitive wiring is ready for sequencing: feel the urge, go to the potty, sit, release.
• Telling you before or during a wee or poo. Even an announcement mid-stream counts. They are connecting the sensation to language. That is a big developmental leap.

Wait for a cluster of these. One or two is not enough. When you see four or five consistently over a couple of weeks, you are in a good window. Do not let nursery deadlines or comparisons with other kids pressure you into starting before you see the signs.

Choose a Method and Commit to It

There are two main approaches. Both work. The difference is intensity and timeline.

The Oh Crap Method

Jamie Glowacki's book (Oh Crap! Potty Training) is the most evidence-informed, practical potty training guide out there. The method works in structured blocks. Block one is commando at home (no nappy, no pants). Block two adds clothing. Block three introduces outings. Block four is handling more complex situations like nursery and longer trips.

You clear your schedule for a few days, stay home, and watch them like a hawk. When you see the pre-wee body language (the tell, more on this below), you get them to the potty. The idea is total immersion. The child cannot rely on the nappy as a fallback, so they are forced to develop the sensation-to-action connection quickly.

It is intensive. It is not actually three days for most kids, whatever the marketing says. Glowacki herself says this in the book, though you would not know it from the social media summaries. Plan for one to three weeks to get to reliable daytime dryness. But it is faster than gradual approaches because removing the nappy creates urgency. There is nowhere else for it to go.

The Gradual Approach

You introduce the potty as a concept weeks before training starts. You let them sit on it at bath time. You read books about it. You let them flush. When they show readiness, you start offering the potty at regular intervals, keep nappies for naps and outings, and slowly shift the balance from nappy to potty over days or weeks.

This is gentler and more flexible. It is better if you cannot clear your schedule or if your child is temperamentally resistant to sudden changes. The trade-off is that it takes longer and the mixed signals from switching between nappies and pants can confuse some kids. The nappy becomes a safety net they are reluctant to give up.

Either approach works. What matters more than the method is consistency. Half-applying the Oh Crap method is worse than fully applying the gradual approach. Pick one, get your partner and any other caregivers on the same page, and do it properly.

What Actually Works: The Commando Phase

If you go the Oh Crap route, or even a modified version of it, the commando phase is the engine of the whole thing. Here is why it works: pants and underwear feel similar enough to a nappy that kids do not notice the difference until it is too late. The elasticated waistband, the fabric against skin, it all says "nappy" to a toddler brain. A bare bottom gives immediate sensory feedback. The child feels what is happening as it happens, which is exactly what you need for them to learn to catch it.

There is a neurological reason for this too. Proprioception, the body's awareness of itself in space, is still developing in toddlers. Bare skin provides far stronger signals than clothed skin. The child feels the first trickle, connects it to the sensation in their bladder, and over a few days learns to recognise the pre-release pressure. That recognition is what lets them hold it long enough to get to the potty.

Practically, this means:

• Nappy off in the morning. Bottom half naked at home.
• Potty visible and accessible in every room they are likely to use. Kitchen, living room, playroom. Make the distance as short as possible.
• Watch for the tell. Every kid has one: a pause, a crouch, a grabbing of themselves, a sudden still expression, a look of concentration. That is your cue. Calmly say "potty time" and move them there. Do not run or panic. Calm and quick.
• Do not ask "do you need the potty?" They will almost always say no. Toddlers default to no. Just prompt at intervals and watch the signals.
• Celebrate catches, but calmly. A matter-of-fact "wee went in the potty, well done" is better than a Broadway-level performance. You want them to internalise this as normal, not as a trick they perform for applause.

Keep them home for the first two to three days if you can. Short outings with a portable travel potty can start once they are consistently catching it indoors. Build confidence before stretching it.

Handling Accidents Without Losing It

This is the hardest part for most dads. And the most important to get right.

You will be on day four. They were doing so well. And then they just stand there and wee directly onto the kitchen floor while making eye contact with you. Or they poo behind the bookshelf like a cat. Or they sit on the sofa and you hear that unmistakable sound.

Your reaction in that moment matters more than almost anything else in this process.

Here is the physiology of why. When a toddler senses frustration, disappointment, or anger from a caregiver, their stress response activates. Cortisol rises. The body goes into a mild fight-or-flight state. And one of the things that happens in a stress state is the pelvic floor tenses up. Tight pelvic floor means harder to release on the potty. It also means more likely to withhold poo, which leads to constipation, which leads to painful poos, which leads to more withholding. You can create a cycle that takes months to undo, all from a few heavy sighs and frustrated reactions.

Frustration, disappointment, raised voices, exasperated sighs: all of these register to a toddler as high-stakes failure. And the response to high-stakes failure is anxiety. Anxious kids do not potty train faster. They stall, regress, or start withholding. You will lose weeks.

The drill is: neutral tone, calm language, clean it up together. "Oops, wee went on the floor. Let us clean it up. Next time, wee goes in the potty." Then move on. No lingering, no big deal. Just forward.

This is genuinely hard after the eighth accident in two days. But the evidence is clear: calm, neutral responses lead to faster training. You are the environment they are learning in. Keep the environment safe. If you feel yourself about to snap, leave the room for 30 seconds and let the other parent handle it. That is not weakness. That is strategy.

Potty Training Boys: What You Need to Know

Boys are, on average, slower to train than girls. That is not a generalisation. It is a statistical pattern backed by multiple studies. Research published in the Journal of Pediatric Urology found boys typically achieve daytime dryness 2-3 months later than girls. Do not compare your son to his cousins or nursery classmates. It will only stress you both out.

A few things specific to training boys:

• Start sitting down. For both wees and poos. It simplifies everything early on. Standing up can come later once they have the concept down. Trying to teach aim and bladder control simultaneously is a lot. One skill at a time.
• Introduce standing later, with a demo. Once they are reliably using the potty sitting, show them standing up works too. Let them see another male doing it. This sounds obvious but it is genuinely the most effective teaching method. Toddlers learn by imitation more than instruction. If you are around, use that advantage. Step-dads, uncles, older brothers all work too.
• The aim thing is a later problem. Do not stress about accuracy early on. A step stool at the big toilet and a target sticker inside the bowl (yes, this is real, yes, it works) can help once they are standing. But this is a phase two concern. Accuracy comes with practice over weeks and months, not days.
• Boys often poo-train later than they wee-train. Normal. The muscles and the sensory awareness are slightly different for poo. If they ask for a nappy for poos for a few more weeks, that is okay. It will come. Pushing too hard here is where withholding problems start.
• Erections during potty time are normal. It happens. It is just blood flow. Do not make a thing of it. If he cannot wee because of it, wait a minute and try again.
• The spray issue. Boys wee upward when sitting on a potty. A deflector guard on the potty helps. Some potties come with one built in. If you are buying new, check for this. You will save yourself a lot of floor wiping.

Regression: What Causes It and How to Ride It Out

Your kid was trained. Dry for weeks. Then you had a new baby, or moved house, or they started nursery, and suddenly there are accidents everywhere again. You are not back at square one, even though it feels that way.

Regression is extremely common after any significant change. The most frequent triggers:

• New sibling arriving. The single biggest trigger. The child's world has just been reorganised around someone else's needs. Regression is a bid for attention and a return to the comfort of being the baby.
• Starting nursery or changing childcare. New environment, new rules, new adults. Overwhelming enough to shake loose recently acquired skills.
• Moving house. Familiar bathroom, familiar potty location, familiar routine: all gone at once.
• Illness. When the body is fighting a bug, bladder control takes a back seat. This one usually resolves fastest.
• Family stress. Parental conflict, bereavement, general household tension. Kids absorb more than you think.

It is not wilful defiance. It is not a sign you did something wrong. It is the child's stress response: reverting to a known comfort behaviour when the world gets unpredictable.

What works:

• Go back a step temporarily. More prompts, more trips to the potty, closer supervision. Not nappies (unless they are asking for them and you decide to allow it briefly). Just more support.
• Do not punish or shame. Same rule as accidents: neutral, matter-of-fact, forward-looking. Shame creates anxiety, anxiety creates withholding. Avoid the cycle.
• Address the underlying change if you can. More connection, more reassurance, more routine. The regression often clears once the adjustment period passes. Spend 15 minutes of undivided one-on-one time with them daily. It sounds small. It works.
• Give it time. Most regressions resolve within two to four weeks without escalation. If it is going longer than six weeks, or is getting worse rather than gradually better, worth mentioning to your GP or health visitor.

Regression is also covered in our piece on the 18-Month Sleep Regression, where the same pattern of disruption-triggered behavioural change tends to show up. Worth reading alongside this.

Night Training: A Separate Project Entirely

This is the one that parents try to rush and cannot. Night dryness is neurological, not behavioural. The body produces a hormone called ADH (antidiuretic hormone) that reduces urine output overnight. Until the brain reliably produces enough of it, the child will wee in their sleep. There is no training intervention that changes the timeline for this. You cannot teach a sleeping child to notice a full bladder any more than you can teach yourself to stop snoring through willpower.

This distinction is important: daytime potty training is a learned skill. Night dryness is a developmental milestone. They are separate processes controlled by different systems. Treat them as two completely independent projects.

The signs that night training might be worth attempting:

• Waking with a dry or only lightly wet nappy several mornings in a row.
• Waking in the night asking to use the toilet.
• Being regularly dry at night for one to two weeks consistently.

Until you see those signs, leave the night nappy on. Most kids do not achieve reliable night dryness until somewhere between ages 3 and 5. Some take longer, and that is within normal range. The NHS considers bedwetting completely normal until age 5 and does not recommend clinical intervention until age 7.

A note on lifting (taking them to the toilet while half-asleep): it is not effective long-term. It empties the bladder, yes, but it does not teach the child to respond to their own bladder signals. You end up training yourself to wake up and carry them, not training them to wake themselves. Use it as a temporary management tool if the washing machine cannot take any more, but do not treat it as training.

Waterproof mattress protectors, layered bedding (protector, sheet, protector, sheet, so you can strip a layer at 3am without remaking the whole bed), and low-key cleanup routines are your friends here.

The 3-Day Potty Training Myth

Let us address this directly, because it causes more parental stress than almost any other potty training claim.

The "potty trained in 3 days" framing that dominates potty training marketing is, to put it charitably, misleading. For a small number of kids in ideal circumstances with very high readiness, the basics can click in three days. But "the basics clicked" and "reliably potty trained" are not the same thing. For most families, you are looking at one to three weeks to reliable daytime dryness, with occasional accidents continuing for weeks or months after that.

That is normal. That is not failure. That is a toddler learning a complex new skill that requires bladder sensation, cognitive recognition, motivation, physical control, and communication all working together. It takes time.

The danger of the 3-day promise is what it does to parents when day four arrives and the kid is still having accidents. You start thinking something is wrong. You start doubting the method. You wonder if your child is behind. None of that is true. The timeline was unrealistic, not the child.

"Consistency is more important than cleverness. There is no hack here. Show up the same way every time and the learning happens."

Common Mistakes That Derail Progress

A few things that tend to slow the process or send it off the rails:

• Starting before genuine readiness because of external pressure, whether that is nursery deadlines, family comparisons, or arbitrary age milestones.
• Inconsistency between caregivers. Different rules with mum, dad, grandparents, and nursery staff. Everyone needs to be doing it the same way. Have the conversation before you start.
• Reacting emotionally to accidents. Covered above, but worth repeating because it is the most common mistake and the most damaging.
• Trying to do it during a period of family disruption. New sibling, moving house, illness, relationship strain. If you are already in chaos, adding potty training to the mix is asking for failure.
• Giving up and restarting repeatedly. This creates confusion and can damage motivation. If you are going to pause, pause properly for at least three to four weeks. Then restart clean.
• Over-rewarding. Sticker charts and sweets for every wee can backfire. The child starts performing for the reward rather than internalising the skill. Some kids then refuse to use the potty when the rewards stop. Keep praise calm and intrinsic.

When you decide to start, commit to it. If you hit a major disruption mid-training, it is okay to pause and restart in a few weeks. But half-training is worse than not starting.

Also worth having a look at our guide on Toddler Tantrums. Potty resistance and frustration around training often overlap with the tantrum phase, and understanding the emotional development context helps. And if you are also thinking ahead to safety as they become more mobile, our Baby Proofing by Age checklist covers the bathroom specifically.

What to Buy (and What Not To)

You do not need much. Potty training is one of those parenting milestones where less gear is genuinely better.

• A standalone potty. Low to the ground, stable, easy to clean. The BabyBjorn Smart Potty and IKEA LOCKIG are both solid. Your child needs to be able to sit with feet flat on the floor for stability and proper pelvic alignment.
• A toilet seat reducer (for once they graduate from the potty). Get one with handles. A step stool to go with it.
• Loose, easy-off clothing. Elastic waist trousers they can pull down themselves. No dungarees, no belts, no fiddly buttons. Independence is the goal.
• Waterproof mattress protectors. Two minimum. You will need a clean one ready while the other is in the wash.
• A portable travel potty for outings once they are past the first week. The Potette Plus folds flat and fits in a bag.

What you do not need: fancy musical potties that play sounds when they wee (distracting and weird), potty training books aimed at the child (some kids like them, most do not care), pull-ups for daytime use (they feel like nappies and send mixed signals).

The Short Version

Wait for readiness signals, not a birthday. Pick a method and apply it consistently. Go commando at home first. Stay calm around accidents, because your reaction directly affects their stress and their pelvic floor. Train boys sitting down initially. Leave nights alone until the body is ready. Expect regression after disruption and ride it out without catastrophising. Ignore the 3-day promise.

It is not complicated. It is just slow, and it requires the same patience that most of parenting requires. You will get there. So will they.
