Oh, I'll try that. The 25 per milk and 75 per water is kind of working. She takes a sip, shoves away the sippy, take another sip. At least she's not spitting it all out.
I also recommend trying out different cups. I have a collection from when I was still trying to get him to start drinking from a sippy or a straw up. It turns out that he only likes the Munchkin insulated straw cups out of the stuff we have. My kid is picky.
