Ds2 is still in bassinet, going into cot next week (if I can clean it out ). He didn't like his arms wrapped in tightly for early on - likes to have arms stretched out above his head. So I swapped him over early to sleeping bags - about 2/3 weeks old. I started by having ds2 wrapped under arms so arms were free to see if he'd sleep better that way (he always used to wiggle them out so I figured I might as well let him sleep that way). He swapped over fairly easily after that.
Ds2 is a fairly good sleeper too and does some self settling and only waking for 1-2 feeds overnight (unless he stirs for a coughing session the past couple of nights)
