10 week old Stopped napping


I have a 10 week old. He has been such a great Napper. Up until Saturday. He all of a sudden is not napping. He has optimal awake time for his age. Up to 90min at times. Goes down super tired falls asleep right away. But is waking up 15-45 min later and not going back to sleep easily. Very weird behaviour for him. Has never done this before. This is happening every nap now and I’m concerned about his sleeping time for a day.

For reference he takes naps in our living room in the pack n play Napper attachment. His usual favourite spot to nap.

Any advice or similar stories at 10 weeks?
