We have been putting Angus to sleep in a bed that last 2 nights but he comes out after an hour or so saying he wants to sleep in his cot!

Mason didn't worry too much about coming out of the cot but Angus loves it.
Can anyone give me some tips on this. We went away last week and stayed in motel rooms and Angus slept in a bed with no worries but now we're home it's the cot ot no sleep :smt022 .
Advice would be much appreciated.
