Sleeping with a blanket

Mary

My LO, just turned 6 months old, sleeps in a pack n play by our bed. I put him in the fleece sleepers so he stays warm. I put him down with a little pillow and blanket and watch him like a hawk until I go to bed. When I go to bed, I take the blanket and pillow. He wakes up instantly! Does anyone else have blanket babies? My husband fusses at me because I freak out with blankets..
