My LO is 7 weeks old now & he isn't sleeping thru the day like he used to. He may sleep 20 to 35 minutes at a time but seems to wake up easily. He seems to want to interact more & is all smiles which is great, but I'm worried he isn't getting enough sleep to develop properly. It seems as though he's fighting falling asleep.
Re: LO not sleeping during the day
So I think your LO is just fine . The older they get the more their sleep schedule turns around to get on track .
