The elimination communication potty training method is based on the idea that babies naturally signal when they need to go. Once you've figured out your child's cues, you can position them over a potty and make a sound (like a whistle or a hiss). They'll eventually respond by peeing or pooping on demand.

Diaper is the generic name in the US for what we in the UK call a 'nappy'. The terms can refer to either disposable nappies or reusable terrycloth nappies. 'Pampers' is a specific brand of disposable nappy/diaper.

Origin of the word In British English, the word nappy originally came from the 'nap' of cloth. However, in American English the term 'diaper' is used. The word 'diaper' was originally the term for a small pattern of repeated geometric shapes.

Diaper is what they use in North America, and Nappy is the word used in the UK & Ireland, Australia, NZ and many other Commonwealth countries.
