Ladies, one of my twins has been inconsolable after feeds, very gassy, appears to be in pain and spits up a ton. Went to peso today and she said he is overeating, like instead of 1/2oz of weight gain a day he is gaining 2oz. I am single side feeding him. (not assigned sides). His sister is not having this problem ( she has a milk protein allergy but that us a different story. So I need advice on how to help my little....or I guess big guy feel better. Thanks!
