DD is two and a half, been in pulls ups for a few weeks now and used the potty about three times a day for wees. Started potty training today. She has consistently started a wee in her knickers, told us then done the majority in her potty. No poos yet which is unusual for her. We've probably done 7-8 changes of leggings and knickers but vast majority of her wee has gone in the potty. Does this sound like a successful first day?
