My LO is 6.5 weeks old and has been on formula since about 2 weeks old. He usually takes between 4 and 5 oz. at each feeding. At night he drains a 5 oz. bottle in 20 minutes or less. But, during the day it seems like he's less hungry. He takes 3 oz. really well, but then seems to hit a wall. He looks around, flails his arms and seems generally distracted. I usually have to force the last 2 oz. down him, and by then end of the feeding, we've been at it for at least 40 minutes.
This morning, for our 7 am feeding, I tried swaddling him (I had the tv off and the room was quiet, and he still was distracted by the blinds and the fan), thinking that with less flailing he could concentrate on the last of the bottle. He took another ounce, but that's it. He was not at all interested in finishing the entire 5 oz.
I did my A time until I saw a big yawn, at which time, I swaddled him and put him down for a nap. It's been about an hour since I put him down, and he's waking up again. Is this because he isn't eating the full 5 oz. bottle or because maybe he's UT and I'm putting him down for his nap too soon. Also, I've been wondering if he might finish the entire bottle if we went to a 3.5 EASY, but since he's waking up an hour into his nap, that seems a little impossible at this point.
What is the best advice to get him to focus and eat the entire 5 oz?
