My son has always been a big eater. He's been eating about 5 1/2 oz per feeding every 3 hours normally. Well starting on Sunday he hasn't seemed that hungry. He only took 3 1/2 oz at his last feeding which was 3 hours after the feeding before. I breastfed him before so I don't know exactly how much he had. He was doing this yesterday too and I thought it was b/c he needed to poop which he did yesterday afternoon but he still isn't eating what he was. He seems happy and doesn't seem sick or anything else. I have called my doctor to see if I should be concerned but wondering if any of you had any ideas. He has been coughing and sneezing a lot I think due to allergies since I don't think he has a cold and since my husband and I have them as well.
