I'm worried that my 20 month old DS is chronically sleep deprived! He gets put to bed around 7.30 - 7.45 and often takes an hour before he goes to sleep (he doesn't usually demand a lot of attention during this time or anything, is just busy standing up and moving around the cot). Then he sleeps well but wakes up 5.30 - 6 (normally closer to 5.30) no matter what time he has fallen asleep or how much of a busy day he had the day before. So typically he is probably only getting 9 hours of sleep a night. He has one daytime nap, around 1.30, and will never sleep longer than an hour (sometimes less). So I really think he is not getting enough sleep. He has also recently started being in an absolutely horrible temper when he wakes up from his daytime nap, I suspect because he is still knackered.
Any suggestions as to how to get him to sleep longer? We have tried blackout blinds which have not made the slightest difference, tiring him out with swimming and stuff in the day also no difference.
He normally has dinner about 5/5.30 and milk before bed, don't know if this is a normal routine for his age?
