My now 6 mth old DS has been taking 1 night feed at about 2:30-3AM for several months now. He basically weaned himself slowly from the other nightly feeds long ago and I have been adding 1 oz of H20 to 4 oz of formula and sometimes he drinks the whole thing and other times he only has about 3.5-4 oz. He does wake a few times per night to be re-plugged still and has been teething for what seems like forever but still no teeth! Should I keep feeding him? I honestly don't think he really needs it but does seem a little thirsty. Should I let him self wean?
