I am looking for help with bottles. I have a 1 year old boy who is now drinking cows milk. He seems to be able to drink out of a glass, but refuses to drink the same from the bottle that I use to formula feed him. I am completely okay with him drinking out of a glass during the day, but for the nights I would like him to drink from a bottle. I have tried the sippy cup for water. He has rejected the sippy cup for water. He drinks water also out of a glass. As a workaround, I am giving him formula feeds at night for now. But my paediatrician also advices me to get him off formula as quickly as possible. I would appreciate any ideas or advice on the kind of bottle to use. I have used Medela Calma for his formula feeds.
