My DS is 18 months and hasn't had any milk to drink at all for the past two weeks. This is since he had three molars coming through at once - it was hurting him to suck from a bottle (which is the only thing he would previously drink milk from anyway). He'll happily drink water from a cup with no lid but won't touch milk from one. I've tried a cup with a straw, a beaker etc etc no luck. He has milk on his cereal, eats yoghurt etc but there is no way his intake is 2/3 pint a day as it is 'supposed' to be. Does anyone have any suggestions or children who won't drink milk and who are still surviving ?
