K.T.
I would just say to keep offering it and she will get used to it. Is she drinking other things from a sippy cup besides milk? If she is ok drinking water or something else from a sippy cup then she will just get used to drinking milk too. Or you could try to just go strieght to regular cups. My friends 1 1/2 yr old drinks from regular cups not sippy cups. He just prefers them. So you could just use a small plastic cup and only put a very small amout at a time and maybe she will like that better. Some children are odd with what they like or don't like. Good luck!
