I started a sippy cup about a month ago, for awhile my baby just played with it a little. I would try to tip it up for her to drink and she would cry. She would however drink straight from a cup. So I started to take the top off the sippy and let her drink, I think she finally realized there was something good in the cup and started drinking out of the sippy top. It did take her awhile, I think, just like with everything it takes practice.
