thanks girls. that's really helpful. yeah Kaz, closing his door has saved him from a mean mummy several times. I only leave him a few mins if he's carrying on, but i really need those mins for some deep breathes.

no haven't changed his diet and have tried cutting back on day sleeps, that didn't help at all.
i suspect its a combo of overtired after his sick night and never catching up on the lost sleep... and behavourial.

i think we might go the big bed and maybe a sleep lullaby thing with a light... and try marching him back... only thing is 4 hours of that and we'll be bigger zombies than atm!

he's mostly been a pretty good sleeper for us since about 7 months and lately would wake occasionally but after a hug and drink of water would be happy to go back to sleep.

hope this passes soon!!

anyhoo any other advice would be greatly appreciated and then we'll work out ao plan of attack.
