DD likes to be independant and tries at nappy change time usually with good results. If she wees in the potty she wipes and in the bath she will wash her face, neck body, bum (in that order) on her own. She's always liked to do stuff for herself though. Saying that I do check and usually she does a good job but will also let me get any bits she's missed if it's especially messy. I think it varies from child to child.
