Any moms on here give their toddlers coconut water? How do they like it. Travis loves milk but it's making him a little constipated(spelled wrong in sure). Like he's going but it's very hard. He drinks water but not enough. He gets bored. And I read coconut water is good for them. Wanna get some advice or feedback before buying it
