I went to my ped today and my LO has gained a pound in 12 days...about 1.3 oz per day..pretty good! However, he is constantly fussy after every feeding and we don't know why. The doctor said to try to switch to a non-dairy diet for a few days to see if this helps. Anyone on this? I have no idea what to eat and what to avoid. I know milk and cheeses, but what else? I'm hoping this is the issue and not colic - I'm going crazy. Any suggestions would be great!!
