Cat napping!?

Becky

My baby boy is nearly 8 months old and sleeps perfectly through the night..No problems. The only issue is that he has up to 5 naps a day and they're never longer than half an hour.. we have tried everything! (Controlled crying, white noise, dark room ect) not sure what else can make him sleep longer? Does anyone else have this problem? Don't see it as a massive issue but I would like him to have 2 long naps so I can get things done lol!
