I have a 5.5 month old formula fed baby. She is on the small side for her age but in proportion. She has CMPA and takes prescription milk. My worry is that throughout the day she barely takes anything from her bottles. Maybe 2-3 ounces but mostly fusses around and wont take any more than that. She has a 5oz bottle before bed and then again in the middle of the night and she gulps those feeds down no problem. Could it be that there's too much stimulation during the day? Is it a sign she's ready to wean? I'm worried because even with the big night time bottles she's still only taking around 20-22oz a day which doesn't seem enough for her age. I only offer the bottle every 3 hours so it's not like I'm giving her it all the time. Help!
