DD has been showing an interest in the loo for the last few weeks and most mornings does a poo in the loo. nursery put her on the loo at nappy change each time and about once a day she does a wee there. she has now finished nursery for the summer; we are contemplating going for knickers in about a month ,as we are away in couple of weeks. should i try and maintain the loo routine till then? or just wait then go for it when I think its time to try knickers?
