Short naps

During the night my 5 week old sleeps just fine (3-3.5 hour intervals) but the last week he has been doing a sleep-eat marathon 😅 he’ll eat, fall asleep while eating, and nap for 15 mins to 30 mins, wake up and eat again, fall asleep, etc. all day long. Anyone else? I’ve kept him awake to feed for longer just in case he’s waking up because he’s still hungry but that doesn’t seem to help..
