My little man is 7 weeks old (3 weeks old for adjusted age) and he has started throwing up his evening feeding. The feeding that falls between 7-9 pm. He never throws up any other feeding and we are feeding the same amount, formula, way as we are all day long. Keeping him upright during and after feeding, etc. pediatrician just shrugs and says if he isn't upset don't worry. Just wondering if anyone else's little one does this. He does have reflux and is on Zantac but has been for 3-4 weeks now and this just started the last couple of days. Nothing has changed.
