Potty training is one of those milestones every parent watches for — and one of the easiest to start too early. The secret is not your child’s age but their readiness. When a toddler shows the right signs, potty training often clicks in days or weeks. Start before they are ready, and you may face months of accidents, power struggles, and frustration for everyone.
Readiness Signs to Look For
Most children show signs between 18 months and three years, but every child is different. Look for several of these together, not just one:
- Body awareness: Your child tells you they have done a wee or poo, or hides to do it, or can feel when they need to go.
- Dry periods: Their nappy stays dry for two hours or more, or they wake up dry from a nap.
- Interest: They follow you to the bathroom, ask questions, or want to sit on the potty or toilet.
- Physical skills: They can walk steadily, sit down and stand up on their own, and pull their own trousers up and down.
- Communication: They can follow a simple instruction and tell you what they need, even with a word or gesture.
- Dislike of dirty nappies: They ask to be changed or seem uncomfortable in a wet nappy.
If your child shows most of these, they are probably ready. If they show only one or two, it is fine to wait — readiness often arrives suddenly.
First Steps: Set Up for Success
Choose the equipment
A potty is less scary than a big toilet for many toddlers, and it lets their feet touch the floor. If you prefer the toilet, add a child seat and a step so they feel stable. Let your child pick the colour or style if you can — ownership helps motivation.
Pick the right week
Start when life is calm: no holidays, house moves, new siblings, or nursery changes in the same week. You will need to be home and relaxed for the first few days, and your child will need your full attention.
Talk about it first
Read a potty book together, let them watch you use the toilet, and explain simply: “When you need a wee, we sit on the potty.” Keep it light and pressure-free. Some children like to practise sitting on the potty with clothes on first.
A Gentle First Week Plan
Day one: dress your child in clothes that are easy to pull down, and offer the potty at natural moments — after waking, after meals, and before bath time. Praise sitting and trying, not just success: “Well done for trying!” If they have an accident, stay matter-of-fact: “Oops, wee goes in the potty. Let’s try again next time.” Never scold or shame accidents; they are part of learning.
By the end of the first week, many children start to tell you before they need to go, at least some of the time. Night-time dryness usually takes much longer — months or even years — and that is normal. Do not rush night training; it depends on hormones and bladder size, not effort.
Common Problems and Fixes
Fear of the potty or toilet
Some children are scared of the flush or of falling in. A potty on the floor, a favourite book to hold, and no pressure to “perform” usually help. Never force a child to sit for long stretches.
Refusing to poo on the potty
This is very common. Some children will happily wee on the potty but ask for a nappy to poo. That is okay for a while — praise the wees, stay relaxed, and try offering the potty at their usual poo time, perhaps with a book or toy to help them relax.
Regression after a change
A new baby, a move, or starting nursery can bring back accidents. This is not naughtiness; it is stress. Go back to basics, offer extra reassurance, and the skills usually return quickly.
Constipation
Holding in poos because of pain or fear can make potty training very hard. Plenty of fluids, fibre-rich foods, and regular toilet time after meals help. If constipation persists, talk to your doctor.
What Not to Do
- Do not compare your child with siblings or friends — the normal range is wide.
- Do not use rewards that grow out of control; a sticker chart is plenty.
- Do not start and stop repeatedly; if it is clearly not working, pause for a few weeks and try again.
- Do not make potty training a battle of wills. A relaxed child learns faster than a stressed one.
When to Ask for Help
Most children are daytime trained by three or four, but some take longer, and that is still within the normal range. Ask your health visitor or doctor if your child is over four and showing no interest, if they have pain when weeing, frequent urinary infections, or persistent constipation.
The Bottom Line
Potty training works best when you follow your child’s lead: watch for readiness signs, set up a calm first week, and treat accidents as learning, not failure. Patience now saves months of struggle later. For more toddler milestone guides, visit the Healthy Baby Guide homepage.
