My DS has recently started at childcare for 1 day a week. They have told me that he is not good at drinking his water and tends to bang cup on table, tip water out or chuck it on the floor. He is 10 mths old. At home I hold the drink for him and encouge him to do so as well but I take it away beween sips as he just plays with it otherwise. I wouldn't have expected him to manage a sipper cup himself yet but now they have got me wondering. Should he be holding it himself and drinking himself by now? When could your child/baby do this?
