sippy cups?

Kari
Has anyone started their babies on a sippy cup yet?? If so how old were they and what kind of silly cup did you get? A picture would be appreciated if you could post one. 
I bought I'm 2 different soppy cups and he hates both. I know it's going to take time for him to love them but even I hated them. I tried sucking on them and it's really hard to get anything out of them... the sippy cup I bought said 6mo+ but i dont know it seems really hard to suck on. 
Is there any kind up sippy cup out there that all you gotta do is chew on the nipple and water will come out??
What did you mothers get if you've started already?
