He generally has three BFs a day -- morning, mid-afternoon and bedtime. I offer water with all meals/snacks and sometimes he has a few sips (straight from cup, he refuses to drink from a spout), but some days he refuses it all day. Is it safe to assume he is getting enough liquid from 3 BFs? (I can;t offer cows' milk as well as he is allergic.) Or should I offer the breast more often?
