Looking for some opinions. My ds is 8 weeks tomorrow and hes formula fed. He was having 5oz every 3 to 4 hrs now its more like 2-3 and hes a very slow feeder. I tried giving him 6oz but he just brought it back up. He suffers with colic and maybe reflux. Recently had to change his milk to comfort as he would spend all day straining then explode out of his nappy.
