Quick answer
During potty training, dress your toddler in soft trousers or leggings with a wide elastic waistband, a loose leg, and no buttons, zips or poppers at all. One-piece clothing — rompers, dungarees, footed pyjamas — is the main thing to put away for a few weeks. Keep three to five full spare outfits within reach at home and at daycare.
Why clothing decides half of this
Toilet training is mostly about timing and patience. The NHS notes that children usually show signs of readiness somewhere between 18 months and three years, and that most parents start thinking about it around two to two and a half — but there is no fixed age, and you cannot rush it. Dutch childcare guidance says much the same thing: interest in the potty tends to appear between two and three.
What clothing changes is the last ten seconds. A toddler often doesn't notice they need the toilet until they really need it. If those ten seconds are spent wrestling with a stiff zip or a popper at the crotch, the accident happens on the way, not because they weren't ready. Parenting and childrenswear guides are consistent on this point: when a child is repeatedly met with complicated buttons, stiff zips or hard-to-reach buckles, they give up on doing it themselves.
So the goal is narrow and practical — make the bottom half of the outfit something a two-year-old can get down alone, fast, without help.
What works, and what to put away
The rule of thumb is: two separate pieces, elastic at the waist, room at the leg. Anything a child has to be lifted out of is working against them.
| Works during training | Put away for a few weeks |
|---|---|
| Soft elastic-waist trousers with a wide, loose leg | Dungarees and overalls |
| Cotton leggings — thicker, forgiving, quick to pull down | Rompers and all-in-ones |
| A simple t-shirt or jumper that ends above the waist | Footed pyjamas |
| Cotton training pants or plain underwear with a soft waistband | Jeans with a button fly, belts, braces |
| Dresses and tunics that sit above the knee | Tights, and long dresses that trail into the potty |
Two details are easy to miss. First, the waistband shouldn't pinch — training pants are often recommended over standard toddler underwear precisely because the elastic is softer and a small child can push them down without fighting it. Second, the trousers need enough room that a child can sit and open their knees comfortably on the potty. A tight, narrow leg makes the whole position awkward, and awkward is what they remember.
This is one of the quiet arguments for an oversized cut: a relaxed leg and a soft waistband are the same features that make a garment last two or three sizes.
The bare-bottom weekend, and what comes after
Plenty of families start with a day or two at home with no bottoms at all. It works because it removes every obstacle at once — the child feels what is happening and gets to the potty with nothing in the way. It also has an obvious limit: it doesn't teach the pull-down step, which is the part they'll need at nursery.
A gentler middle path is to keep the child in underwear or training pants at home and add loose trousers on top only when you go out. That way the skill of pulling down gets practised, but it's practised on the easiest possible garment first. Once that's reliable, ordinary elastic-waist trousers are a small step, not a new problem.
Accidents, spares, and how much laundry to expect
Accidents are part of the process, not a sign it's going wrong. Plan the wardrobe around them and the whole thing gets less stressful.
- At home: three to five complete outfits — trousers, underwear, socks — stacked somewhere low and reachable, ideally by the bathroom rather than in a bedroom cupboard.
- Socks count. They are the piece everyone forgets and the piece that gets wet first. Dutch childcare checklists explicitly list socks in the spare bag for this reason.
- Label everything. Nurseries ask for named clothing because spare garments circulate between children constantly.
- Wash cool and often. Frequent short cycles at 30°C are kinder to organic cotton than occasional hot ones, and they keep the rotation moving.
This is also the stage where hand-me-downs and second-hand pieces earn their place. Training weeks are hard on clothes; wearing something that has already lived one life takes the sting out of a stain. Our Twice Loved pieces exist for exactly these months.
Daycare, outings and the Dutch weather problem
Dutch childcare guidance is blunt about clothing: avoid anything that's difficult to get on and off, because staff have to remove layers every time a child goes to the toilet. In a group of twelve toddlers, a pair of dungarees is a genuinely slow garment.
Outside the house, the complication is layers. A rain suit or a thick winter overall adds thirty seconds to every toilet trip, and thirty seconds is often the whole margin. Two things help: choose outer layers that open fully at the front rather than pulling over the head, and build in a toilet stop before you dress for the bike, not after. On rainy days, a rain suit worn over quick-drying trousers is more forgiving than one worn over thick joggers that stay damp for hours.
Regression around a new nursery, a new sibling or a house move is common and usually temporary. Training pants are a reasonable bridge during those weeks — they keep the pull-up-and-down routine intact instead of sending everyone back to nappies.
FAQ
At what age should we start potty training?
There's no fixed age. NHS guidance puts the usual window for signs of readiness between 18 months and three years, with many parents starting around two to two and a half. Readiness looks like noticing when they're weeing or pooing, and being able to sit down on a potty and get back up unaided.
Are training pants better than normal underwear?
They serve different moments. Cloth training pants have a softer waistband and a little absorbency, which suits the first weeks and any regression period. Once accidents are rare, plain cotton underwear with a soft elastic waist is simpler and cooler.
How many spare outfits should I send to daycare?
Two to three complete sets during active training, including socks, all named. Nurseries keep a communal stock, but children are more comfortable in their own clothes — and the communal box empties fast.
Should I buy a size up so it's easier to pull down?
A relaxed fit helps, but a waistband that's genuinely too big will slide down while they run. Look for a wide, soft elastic waist and a roomy leg rather than simply a larger size — that combination gives you the ease without the sagging.
What about night-time?
Dry nights typically come well after dry days, and that's normal. Two-piece pyjamas with an elastic waist make a night-time trip possible; footed sleepsuits don't. Keep a spare set and a mattress protector within arm's reach of the bed.
Do dungarees ever come back?
Yes — once a child is reliably dry and can manage the fasteners themselves, usually somewhere past three. It's a pause, not a farewell.
