DD is 5.5mo and has just moved into her big cot (we have a stokke sleepi so she was in the small crib until now). She is a nightmare to settle in her bigger cot - rolls around, up on her front looking around, gnaws at the bars, gets herself stuck, generally screams 
I've been up for an hour and a half resettling her and am on my knees 
Do these cot acrobatics ever stop? Is there anything else I can do to just.bloody.make.her.sleep?
