Maybe a bit strange but is anyone else's baby noisy when sleeping?
My little boy is nearly 4 weeks old and when I feed him during the night and then put him back in his basket he makes sort of grunting noises for a few mins before settling (he's not crying and his eyes are either completely or mostly shut)
He sometimes does it in his sleep too but when I look to see if he's awake for food he's asleep 
We now have a sleeping bag for him which made things a bit better last night.
Is it just him settling? He doesn't seem upset as I always pick him up if he is.
TIA
