My DS (15 months) is very active in his sleep and insists on sleeping across the bed (just like his dad apparently so we shall blame him). This was fine until he started getting his legs stuck in the cot bars and waking up screaming 2 to 3 times a night as he tried to roll over with his legs in the bars
.
Thanks to the recommendations on MN I bought an AirWrap bumper and this worked well for about a month until he worked out that he could push the AirWrap down and still stick his legs through 
So in fear of him seriously hurting his legs we changed his cot into a bed and a nightly battle to get him to sleep began.
In his cot he would play around for a bit and then settle himself and go to sleep around 7.30pm. Now no matter how tired he is he views bedtime as this big game. So far we have tried SuperNannys stay in bed technique for over 2 weeks with absolutely no effect (he enjoys being walked back to bed!) so I think he is a little bit young for this as he just doesn't seem to get it.
I think the main problem is the fact that he is so young, but I feel like we can't put him back in the cot for fear of hurting himself.
Once he does finally go to sleep then he sleeps right through
, but this messing about in an evening is making him more and more tired and irritable during the day.
Does anyone else have experience of this and please does anyone have any suggestions so I can get my evenings back....
