bottle woes

We are trying to wean Kian off of the bottle and on to the sippy cup. Oh my goodness! It has been awful. This child does not want to drink anything from a sippy cup. He looks at me and screams when I try to offer the cup with formula in it over the bottle. He no longer gets the bottle during the day, just when he wakes up or goes to bed. Umm, yeah, I guess that means he's not really drinking during the day. I'm REALLY hoping that he adjusts the next few days. He takes a couple of sips if it's juice, but that's about it! Any suggestions? I don't really remember how we did it with Aiden. Right about now I wish I would of journalled everything when Aiden was little! It's so funny when Kian even sees the bottle on the kitchen counter he screams in anger, as if to say, "I know what you're trying to do and I don't like it!".
