Long story short - DS 9 months has never been a good sleeper, now wakes about 4 times a night which is tough but main problem is getting him off to sleep at night. It can take hours.... Tonight he is still wide awake and refusing to sleep. I do everything you would expect, bath, dark, quiet, soothing no fun and games.
He's a great day napper, easy to go down regular. Just night is hard work. He regularly sleeps 8-10 hours a night.
Do some babies just need less sleep? DH doesn't sleep a lot, he does maybe 5 hours a night, could it be genetic?
