My 21/2 year son does wants to drink milk in glass or sipper straw bottles except feeding bottle. How do I stop this habit from having milk from feeding bottles . I am worried about his calcium intake . He doesn’t like to eat curd or ragi too . This is my biggest concern ? Can any doctor or expert advise how to offer him milk and switch from feeding bottle to other source . For taste purpose I’m using milk shake powder too slurp once but of no use he is refusing to take milk in glass or sipper cup / bottle too
