LO will be 4 months in 2 weeks... He started day care for 2 afternoons this past week. When I went to pick him up they told me they gave him water because he wouldn't stop crying and nothing they would do would help.. So they gave him an ounce of water and then fed him his bottle which he ended up only eating about 4 ounces. I've been reading that babies shouldn't be drinking water until they are at least 6 months old. Opinions?
