Is Your Toddler Ready for Potty Training? Signs to Look For

Is Your Toddler Ready for Potty Training? Signs to Look For

Using the potty is a brand-new skill. Your child has to notice the urge to go, get to the potty in time, manage their clothes and choose the potty over playing. Children put those pieces together at different ages, so here's what to look for.

What age do toddlers usually start potty training?

Experts give a range, not a single age. The American Academy of Pediatrics (AAP) says signs of bladder and bowel control generally appear between 18 and 24 months. In the US, the average starting age is between 2 and 3, and most children are bowel and bladder trained by 4. Nemours KidsHealth adds that boys often begin later and need more time than girls.

Where experts differ: most sources suggest watching for readiness signs before you start. The NHS in the UK says nearly every child can learn between 18 months and 2½, and suggests starting then without waiting for signs. This article follows the readiness-first approach of the AAP and most others.

Signs your toddler may be ready

The AAP describes using the potty as a mix of body awareness, skills and willingness. The signs below come from the AAP, the Canadian Paediatric Society, Nemours KidsHealth and KidsHealth NZ. Your child doesn't need to show every one (KidsHealth NZ).

Body

  • Stays dry for 2 hours or more at a time, or wakes up dry from naps
  • Has regular, soft poops
  • Shows when a pee or poop is coming, for example by grunting, freezing or squatting

Skills

  • Follows simple instructions
  • Walks to the bathroom and sits steadily for a few minutes
  • Helps pull their pants down and up
  • Tells you, in words or signs, that they need to go or just went

Interest

  • Dislikes wet or dirty diapers
  • Is curious about the toilet, or follows you to the bathroom
  • Asks to use the potty or to wear "big-kid" underwear
  • Wants to do things on their own

If you see several of these over a few days and life is fairly calm, it may be time to plan your start.

When it may be better to wait

The AAP, Nemours KidsHealth and Cleveland Clinic suggest waiting until things settle if your family faces a big change. That includes a move, a new baby, a separation, a serious illness, a death or another crisis. Nemours also suggests waiting during travel, a move from crib to bed, or an illness, especially diarrhea. It adds that starting too soon tends to make the process take longer.

Check for constipation first. The NHS says a child should have soft poops at least every other day. Hard, dry or pebble-like poops, or straining, can be signs of constipation (NHS), which can make toilet training harder (KidsHealth NZ). If you notice them, talk to your child's doctor before you start.

If your child has special health care needs, ask your pediatrician how to adapt these tips (AAP). The NHS notes that children with disabilities or special educational needs can still learn, with more time or support.

Getting ready before day one

  • Gear: a potty chair, a seat for the big toilet, or both. With a toilet seat, add a step stool so your child's knees are higher than their hips (NHS).
  • Easy-off clothes: elastic waists come down fast. Overalls, buttons and zippers take longer (Nemours KidsHealth, NHS).
  • Friendly words: pick positive words for pee, poop and the potty, and skip words like "dirty" or "stinky" (AAP, Nemours KidsHealth).
  • Practice: read potty books, let your child see you use the toilet, and let them sit on the potty dressed (AAP, NHS).
  • A calm start date: plan a few days at home or close to home (KidsHealth NZ). Tell other caregivers your plan (Canadian Paediatric Society).

Underwear or pull-ups? Experts disagree. The AAP and the NHS favor underwear (or cloth or reusable training pants) by day. Nemours KidsHealth and Cleveland Clinic see disposable training pants as a possible in-between step. KidsHealth NZ's advice: whatever you choose, stay consistent.

The first few days

There's no single right method, and the AAP says any approach may work. For the first days, the sources suggest:

  • Offer the potty at set times, rather than waiting for your child to ask every time (NHS). Try first thing in the morning, after meals and snacks, before and after naps, before you go out, and before bed.
  • Keep sits short, a few minutes at most, and never make your child stay against their will (Nemours KidsHealth).
  • Praise every try, even when nothing happens (Nemours KidsHealth, NHS).
  • Use a diaper for naps and nights for now (NHS).

Give it time. Nemours KidsHealth says training often takes 3 to 6 months, and it can take more or less. Many children pee in the potty well before they poop there, and dry nights often come months or even years after dry days (AAP).

When accidents happen

Accidents are an expected part of learning for most children (NHS). When one happens:

  1. Stay calm. Try not to get angry or upset (NHS), and don't punish or show disappointment (Nemours KidsHealth).
  2. Keep it simple. Say it was an accident, it's okay, and you know they'll do better next time (AAP, Nemours KidsHealth).
  3. Change them and move on. Remind them to use the potty, since busy kids can forget (KidsHealth NZ).

If your child refuses, gets upset or nothing is clicking, it's fine to take a break. Sources suggest anything from a couple of weeks (KidsHealth NZ) to about 1 to 3 months if your child refuses the potty (Canadian Paediatric Society).

When to talk to your pediatrician

Most bumps are a normal part of learning. The sources below say to call your child's doctor about:

  • Pain, burning or straining when peeing, or pain when using the potty
  • Blood in the poop or on underwear, or pink, cloudy or bad-smelling pee
  • A sudden change in how much, how often or how urgently they pee
  • Constant dampness, dribbling, a very thin stream, or leaks when coughing or running
  • Redness or a rash around the vagina
  • Holding in poop, or signs of constipation
  • Poop leaking into underwear, often unnoticed (it can be a sign of constipation)
  • Pooping on the potty still a struggle after two or three months
  • Vomiting, a swollen belly, or changes in eating or weight, especially with poop problems
  • After 6+ months fully trained: slipping back, new bedwetting, or wetting day and night
  • A sudden change in mood or personality, or new problems with walking
  • Being 4 or older and not yet using the toilet

Also call if your child is going backwards: the AAP's first step is a checkup to rule out a physical cause. And call if training is very stressful for your child or you, or any time you're worried.
