Nurseries and pre schools (taking children from 3) expect the child to be toilet trained and to be able to drink from a normal cup. The previous advice re using the search on toilet training is good. I do not have a boy so things may be different but my 2 1/2 year old girl is now fully trained by day-it was just a matter of getting her used to the potty..getting used to mopping up accidents too! Now it drives me mad-we are up and down to the toilet all day long! I almost wish she was still in nappies! Great to save the money on nappies though.
