When did you do it? Any dramas? Is there an age that it is easier or harder? Did you start just for day sleeps initially?
DS is nearly 8 weeks and while all is ok in the bassinet now, I've tried a couple of times to put him in the cot for day sleeps but he obviously notices it is different (much less cosy!) and won't sleep there at all. He's not generally a good day sleeper anyway but has just started sleeping through the night every now and then, so maybe I should just put him in the cot at night when he gets too big for the bassinet. I'm terrified of messing up his amazingly good night sleeps though if he won't settle in the cot!
