M.M.
I've been there! First of all, dont put milk in the bottle at night, I was told it would spoil the teeth, put water in it instead. My daughter had a fit and so I just gave her a spill free sippy and she was happy, she's now 2 3/4 and still has a "water" sippy at night. She also cried until she made herself sick. And she picked out the sippy cup. Took awhile before she gave up the bottle completly.
