My 10 month old DD has always drank out of a doidy. She'll be starting nursery next week and the workers there say that although they have no problem with her using doidy (she can just pick it up and drink from it herself), they are worried that because it doesn't have a lid, the other babies might throw things in her water. I'm not keen on her using a sippy cup - even if I could train her to do so - but what's the alternative?
