Favorite sippy cup?

[heygrey]

i didn't answer in the other thread so i'll answer here

i tried a few soft spout sippies and all were rejected with the same passion that he rejected bottles. i figured i'd get a straw cup, but saw the Rubbermaid juice boxes on sale... so why not try? he took too it immediately. and from what i gather from sippy chatter, the sooner they're on a straw cup, the better. may as well start with one and see if your baby can figure it out! if she doesn't, it will be useful eventually so no money wasted.
