4 wo fell asleep while waiting for bottle - to wake or not to wake
My 4 weeks old (EFF) woke up around 3am and my husband fed him 150ml. He fell asleep shortly after and I put him back in his crib to sleep. He woke up around 5.30am, a shorter time frame than usual (about 1-2hr earlier than I expected) seemingly hungry. I stalled a few minutes then tried the paci to see his reaction and he attacked it lol and started fussing and crying so I prepared him a bottle, he got increasingly hangry while waiting for it to cool down so I picked him up and tried to calm him down with contact and the paci. Then he fell asleep and now (6.40am) he is deep asleep. Before getting him back into his crib I caressed his mouth the paci and my finger but he kept it closed.
Should I have tried to wake him up and feed him?
Additional context- I am a FTM and we’ve been trying hard to get an undestranding of how much he should be eating to avoid over/underfeeding.
His birth weight was 4kg, then dropped to 3.5 in the first week since I had no milk and we have been formula feeding since then,m.
The second and third week he gained steadily (3.9kg and 4.3kg,m), this week seems like he gained much less (4.35kg). Ped suggested increasing quantities and feed him until he is full but he very rarely seems full, if we dont take the bottle away he keeps on sucking (we practice paced eating to make it last longer)… and 150ml a bottle for a 4wo seems like a lot already? However he did not gain much this week.. i am confused! Opinions?
