I've been giving LO a 4 oz bottle of formula a day since we're going out of town and my freezer stash is short by one day. We started about a week and a half ago and she took the bottle just fine. She did get pretty fussy/crabby for a couple days but I wasn't sure if it was the formula introduction or something else (wonder week, 4 MW, etc). At one point I considered contacting the pedi because she was so inconsolable at times. I switched her from Similac advanced to Similac for fussiness and then she turned a corner and my happy baby was back (like, sleeping like she's never slept before, so happy and smiley, etc).
Then last week, I googled something about Similac for fussiness and it came back that the first two ingredients are corn syrup and sugar. I was pissed! I'm not exactly crunchy granola or anything but there's just no reason for my almost 5 month old child to be getting corn syrup and sugar right now.
Now I switched AGAIN and my fussy/crabby baby is back. Is it possible that the Similac for fussiness really did THAT much for her and this new formula is upsetting her stomach again? How long does it take for them to get used to a formula?
Thoughts? Sorry for the novel. TYIA!
