hello, i have started ec with my nearly 17mo dd a few days ago. So far just been leaving her nappy off in the morning, bathtime and nappy changes. She seemed excited about sitting on the potty at first but that didnt last long because she screams and screams if i try and sit her on it and keeps throwing it across the room if i even just ask her. Is she too old for ec? She talks about wee and poo a lot so i thought she might be ready. Really wish i had known about it when she was much younger.
