LO is EFF and now that he's 6 months my doc said it's ok to give him sips of water and to start using a sippy cup. It's super hot out where I live so I've been wanting to give him some water, but he doesn't know how to use the cups yet. What's the best way? I got the Munchkin 360 and straw cup and he's clueless as to what to do with either of them. Any tips for teaching him? Or any cups that are easier for a first-timer wh doesn't really get it? I was staying away from sippy cups with spouts after everything I read about them affecting speech development but now I'm thinking maybe that's what we need. Any tips?
