It's been cold, so I've been making sure he is nice and cozy in bed. I bought "blanket sleepers" so I could zip him up in those and not worry about a blanket. But I'm always cold, and try to keep the baby warmer than myself, so I've also been putting the crib blanket on him. (Tucking him in, then tucking the blanket on each side of the mattress tightly, so he can't pull it up over his head.)
It looks like this kid is hot-blooded like his dad and sister, though. Last night he managed to get that blanket loose and kicked it completely off. And slept. All night.
