I have a 4 month old son. Lately his appetite has greatly decreased. I pump and bottle feed (due to his reflux and the position he needs to sit in), so I can monitor his milk intake. He used to drink about 20 oz of bm every day. Now he's down to 13-17 oz, and he's been this way for a few days now. He doesn't have a temp., doesn't seem to be cranky, and doesn't seem to be teething. I'm not sure what's up with him! When I try to get him to drink more, he just plays with the nipple of the bottle, or turns his head, or starts crying. When he will drink more, he just throws up A LOT of it. I would say that he's had a decreased appetite for about 4 days now, and he's thrown up a lot of bm for 2 days now. Can you explain what's going on w/ him? Should I be concerned or is this normal baby behavior?
