Cot/bed

I have mine in a regular adult bed but it's low to the ground and I ordered these sausage looking bumper things on Amazon that tuck under the fitted sheet to keep them from rolling out and they have worked great.

ah that sounds good! And do they manage ok with a blanket and pillow?

Mine usually throws off the blanket and moves so much that he hardly stays on a pillow lol

Dress them in temperature appropriate pajama that acts as a blanket

We are actually moving our son to his twin bed next weekend. He has slept in an adult bed before without a problem. He sleeps with a pillow and a blanket at the moment, and he just throws the blanket to the side, sometimes he pulls it back on him. His twin bed it's actually a floor bed, with rails. He does move A LOT so I think the bed will be good for him, and the crib is getting small for him
