Hi, so my amazing sleeper has suddenly become not so amazing. He jumped out of his cot a couple of weeks ago so now in bed. Ever since he needs me in his room to fall asleep and has began waking during the night calling for me to sit in his room, If I don't all hell breaks loose. Looking to do the put back in bed method next week (if I find the patience) just wondered about what music people use for their toddlers to fall asleep? Anything you would recommend? Do you leave it on all night long? Thanks x
