This NHS- and ERIC-aligned guide walks you through readiness signs, a realistic 3-week plan, and what to do when it doesn’t go to plan. Reviewed by the Nursery Advice editorial team Last updated 31 May 2026 Next review 30 November 2026 [Editorial standards](/parent-hub/editorial-standards) General guidance, not medical advice Follows NHS and ERIC (The Children’s Bowel and Bladder Charity) guidance current as of the review date. If your child is over 3.5 and not showing readiness signs, or has chronic constipation or daytime soiling, speak to your GP or health visitor. Potty training is one of those parenting moments that looks tidy on Instagram and chaotic in real life. The good news: the NHS[1](#source-1) and ERIC[2](#source-2) agree that the single biggest predictor of an easy training is **waiting for readiness** — not starting at a specific age. This is a calm, evidence-based 3-week plan that works for most children once they’re ready. It’s slower than the "3-day method" but with far fewer regressions and tears. ## When to start: the readiness checklist Most children are ready between **2 and 3** years old. Look for several of these signs together, not just one: - Dry for 1–2 hours at a stretch. - Tells you (or hides) when they’re weeing or pooing in their nappy. - Can pull their own trousers up and down. - Shows interest in the toilet/potty or in others using it. - Has bowel movements that are predictable (often after meals). - Can follow a simple two-step instruction. Pick your window Choose a 3-week stretch with no big changes — no new sibling, no nursery start, no holiday. Long weekends are gold. ## The kit you actually need - 2–3 potties (kitchen, lounge, upstairs). - A child toilet seat and step stool for when they move up. - 15–20 pairs of pants — they love picking them. - A waterproof mattress protector. - A picture book about potties for bedtime reading. - Wipes and a couple of changes of clothes in a bag for outings. You don’t need pull-ups for daytime training — ERIC specifically advises **going straight to pants** because the wet sensation teaches the body to notice. Save pull-ups for nights and naps until you’re ready to drop those too. ## The 3-week plan ### Week 1 — at home, pants only - Stay home for 3–4 days if you can. Pants only, no nappies. - Offer the potty every 30–60 minutes — after meals, after drinks, after sleep. - Celebrate sitting on the potty. Mega-celebrate using it. Stay matter-of-fact about accidents: "Wee goes in the potty. Let’s clean up and try again." - Read the potty book at every nappy-time anyway. Repetition matters. ### Week 2 — short trips out, still in pants - Quick trips: park, shops, friends. Always go to the toilet before leaving. - Take a portable potty and a change of clothes. - Expect 2–4 accidents most days. This is normal and stops by week 3 for most children. ### Week 3 — normal life resumes - Drop the 30-minute prompts. Trust them to ask, but offer at obvious times (waking, meals, before outings). - Move from potty to toilet seat if they’re willing. - Tell nursery you’ve started — they will absolutely back you up. Send 4–6 changes of clothes. ## Nights and naps Daytime and night-time dryness are separate processes. Night dryness is largely _hormonal_ — your child’s body has to start producing enough antidiuretic hormone overnight to slow urine production. That happens on its own timeline, usually between **3 and 5 years**. There’s nothing you can do to speed it up. Wait for **14 consecutive dry nappies in the morning**, then drop the night nappy, put a waterproof on the mattress and expect occasional accidents. If your child is over 5 and consistently wet at night, speak to your GP — it’s common and treatable. ## When it doesn’t go to plan - **Refusing the potty after a few good days.** Pause for 2–3 weeks, no fuss. Try again. Many children need two runs at it. - **Holding poo / constipation.** Very common. Increase fluids and fibre (pear, prunes, kiwi), keep them moving, and stay relaxed about it. Long-term holding warrants a GP visit — see ERIC’s resources.[2](#source-2) - **Lots of accidents at nursery only.** Settings have lots of distractions. Ask the key person to use timed prompts for the first week. - **Wetting after weeks of dryness.** Look for a trigger — illness, new sibling, starting nursery. Usually short-lived. When to see the GP See your GP for: a child over 4 who isn’t dry in the day; recurring UTIs; severe constipation; or daytime soiling after a previously dry period. These are common, treatable problems — don’t wait. ## Frequently asked questions Is 18 months too early? For most children, yes. Bladder control and the ability to follow instructions usually develop between 2 and 3. Starting before readiness signs almost always means a longer, harder process. Should I use a reward chart? They can work for some children for a week or two, but most paediatric continence specialists prefer warm verbal praise. Sticker charts can backfire if children become anxious about not earning a sticker. My child is dry in the day but still pooing in pants. Normal? Very common. Pooing on the potty often comes weeks after wees. Don’t pressure — offer the potty after meals and at bedtime, keep the loo a calm place, and treat any constipation early. ## Ready to find a brilliant nursery?
