My 7-month-old absolutely loves water. I think it's a combination of the hot weather, cold drink, and just wanting what we have. It's great, because it's amusing, but it'd be nice if we didn't have to make sure that he wasn't damaging his teeth whenever he chomps down on glassware. It's also be nice if there wasn't a huge mess every time we fed him water at a restaurant. It'd also be fabulous if we didn't have to hold the cup for him.
