Short awake time?

Nicola

My baby is almost 13 weeks and I don’t know whether to be concerned about his awake time. He’s an notorious catnapper of 40mins but I manage to get him into his second sleep cycle once or twice a day. However he seems to be incredibly grumpy about 20 minutes after he wakes up and wants to go to sleep again. I have to basically change activities every two minutes to make him stay awake for 45-1hr. If I try to put him down earlier, at his “tired signs” he fights it until an hour rolls along!

Does anyone’s baby do the same thing?
