She is only 19mths and insisted on potty training due to a sister who is 12mths older. Now its a bit of a pain as she cant quite pull knickers up and down but thats not a problem. However she is 100% reliable bare bottomed and in knickers however if I throw trousers into the mix she wets every single time. So what do I do? I know she is still very tiny and a lot younger than my other 2 were so they were very capable of pulling up and down knickers and grasping that if they had trousers on they still had no nappy.
