Having serious struggles even getting the Little Guy to sleep in the cot.
No matter how asleep he is when I put him in there, he has never once slept in there longer than 20minutes.
But, If he sleeps in the middle of our bed he gets a great and usually lengthy snooze.
I think it's because of the closed in feeling (HATES the carseat too) and the fact that that as soon as he shifts he bangs himself on the side. He's a real acrobat.

The cot is just for show really as I've totally given up on it. However he takes up more room in the bed than DH and I'm a bit over it really.
We do have a trundle bed (ie low low to the ground) and I've been seriously contemplating just getting a soft bed rail and putting him on that. He's very mobile and can climb up onto the kids lounge and the rundle is no higher than that.

Has anyone tried a bed this early? (he's only 10months)
