How is moving him to a cot going to stop him moving under the blankets? Wouldn't there be more room for him to go under them?

I thought seen he is
wriggling in his bassinet, so his feet are in one corner and his face is pressed up against the opposite side. When he does this, he also wriggles deeper under the covers, so they cover part of his face.
He sleeps in a Woombie, and I place him with his feet at the bottom of the bassinet, with the covers pulled up to his shoulders and tucked in tightly. So, I'm thinking either he needs more room and is ready to move into his cot
it would be safer in the cot. Sorry if I mistook the question- I thought she was worried about the positioning of her DS... I dont think there would be any difference in him being able to go under the blankets if he stays in the wombie...
