M.M.
It took me some time to get my daughter to switch from the bottle to the sippy cup. She will only use the cups with the hard spout and at first would only take juice or water from the sippy cup. I finally just put all of her bottles up and did not give her a choice. After a day she decided to drink her milk from her sippy cup and has not tried to drink from a bottle since. Good Luck and hang in there.
