What are your thoughts on using a magic bag drapped accross babys lower tummy and legs.

My LO seems to like the weight and heat of it and he falls asleep so quickly with it on. Its comfort for him. But i dont know about leaving it on when I'm not there.

He usually fusses and wakes if its not on so i have to stay there with him.

I do have a camera to see him when im not in the room.. but still.

Thoughts?
