Does he seem tired Art? Doesn't sound like a lot of sleep for his age but I guess they are all different. Is he a really active kid? Maybe try some activities that will get him really tired lol! DD is a few months older than your DS and she sleeps 11-12 hours overnight and between 1-1.5hrs after lunch most days. She does skip her day sleep maybe 1-2 days a week but has it every other day.

Hopefully he will sleep longer overnight when he goes to kindy/school! That should tire him out lol! Your poor thing, I can definitely understand the need for kid free time!
