Q:My one year old keeps taking her nappy off.Surely it's too early for me to start potty training her?

A:She's quite young for this at one.For potty training to succeed,a child needs to be physically and emotionally ready,as well as willing to cooperate.
  Do respond to her behaviour,though.She's letting you know that she's learning about her body - how it feels with and without a nappy,wet or otherwise.Observe her to see if there are signs of recognition of different bodily functions,such as staying still while she wees or straining to poo.Talk to her about what she's doing - 'Does your nappy needs changing?' or even,'Do you need to use the potty?' You may find she's more comfy without a nappy - but be prepared for mess.
 Another response is to try training pants - these absorb wees and poos but,unlike a nappy,your child will immediately feel wet.This allows you to introduce the next stage while still providing the security of a nappy.
