I put my lo down about 7:30 each night however rather than going to sleep he will lie awake waiving his little arms around like he is doing karate, making noises like he is a bit upset but not actually crying. Often this will last 45-60 mins and then he will fall asleep, but other times he will startle and then start crying, working himself up to a state where we have to pick him up to settle him.
It's not a problem as such, but I am curious to know whether anyone else has experienced this / has any thoughts why he does this?
