Dear Doctor
I've got a 5 months old baby boy. I'm breast feeding which is very tiresome. I'm trying to give him optimal formula. He will take 2ozs and then he will burp. Put him to bed and after an hour he will wake up vomitting. He will do this 3 times and the third time he starts bringing up bile. Then he will have diariahha twice. He is very tired afterwards until about couple hours after he will wake up. I will put him on the breast which he will drink as normal.
This morning I tried him with baby oats porridge which he took ok, went off to sleep and the same procedure as the milk occurred
Can you please advise what is causing this problem
