Just read that it is safe to give tap water( on another thread. Am quite pleased as I always boil and cool. Thing is my DD(9months) has started refusing water from her sippy cup. She used to take it with juice but she seems uninterested now. She has about 20 ounzes of formula a day and an evening bf. Just a bit worried as I am sure she can't "not" have water, even though formula is made up with water. How much water do your LOs have??
