My 7 month old DS has always been a co-sleeper with me (daddy is in another room). He has in the past fallen asleep in his cot and will stay there all night) but just this past few weeks he will literally scream and scream in there until I take him out to sleep with me.

Im just scared now that he will 'roll' out of the big bed.

How can I get him to start staying in his cot. Another thing is he moves around now (crawls backwards) and gets his little foot stuck. He has a Leapfrog Tadpole that plays lullabies which used to always make him fall asleep.

His two top teeth are cutting through too.

I dont want him to scream and scream all night. How can I get him back to his cot.
