Hmm ~ never come across this issue so not sure how I would handle it ... been blessed that my crew all sleeps really well OR if they have outgrown their nap they at least rest quietly to respect the others need to nap.

I personally do not care if they sleep or not as long as they REST so I can get a break and so that the others who still need a longer nap can have their needs met.

Is there a place you can put him to minimize the disruption ~ aka so that if he is awake he is not disrupting the sleep of others and than just train him to 'shhh quiet time lay down' and keep laying him back down until he gets that this is the expectation cause that is young to have such a short nap so am wondering if he is waking mid sleep cycle and does not know how to 'self soothe' back to sleep for longer?
