That's not comfortable.
I'm not sure I've mentioned this before, but Luke sometimes likes to use my face as a pillow. It's usually when he's tired and scrambling around the bed a little and no, it isn't comfortable. I'll usually let him do it for a little while, as long as it helps settle him down. Yesterday when I was putting him to sleep, he was holding his baby (the Gloworm I told you about before). It's head was resting right on his face.
