Hi, I started a sippy cup with Owen a few days ago and he learned how to use it pretty fast. Naturally he can't bring it to his mouth alone, he tries but it goes in his eye, hair, ear... so I help him. I was wondering - is it ok to put formula in it? I don't want to confuse him. I think water is fabulously healthy, but it seems so empty for this age. Whatcha think? Thanks.
Love,
Zoey
Oh ps, he only take maybe a half ounce in the sippy.
