19 months old and after periods of being a nightmare sleeper up until 1, became a good sleeper. Recently began waking and climbing out of cot so decided to get him a tooddler bed with rail. Unfortunately he hates it and as soon as you put him down he springs back up screaming, crying and climbing out. We've spent the last few nights in his room with him sat next to his bed, stopping him from getting out etc. until he eventually screams himself to sleep. This ha staken about 3 hours each night. Once asleep he only sleeps for about 6 hours then jumps out again. Have thought about shutting the bedroom door and letting him stay in his room by himself, crying etc.,as he will definately jump out of his bed if left alone. Any advice would be hugely appreciated as I am 7 months pregnant, and can't cope with the lack of sleep and stress!!
