Please help!! DS is 19 months old. He slept well until recently (7pm to 5-6am) and I used to be able to put him in his cot and walk away. He'd either go straight to sleep or he'd happily roll around for a few minutes and then sleep. No crying and no more than 20 minutes to sleep.
Now though it takes over an hour and a half to get him to sleep. As soon as I leave the room he's standing crying. So I tell him to lie down, and he does for a few minutes and the stands again. This goes on regardless of whether I go back to him straight away or leave him for a few minutes.
So tonight I thought I'd sit in with him in his room. We've been here now since 7pm and he's rolling around, chattering, just playing. No crying though because I'm here. So that isn't the solution. Help please!! He's still waking up before 6am so he's tired!
