If you can imagine being simultaneously crushed and smothered, Lana, you get the idea. If I push him off and turn over, he climbs on to my shoulder.
Last night he jumped on the bed and walked on my right ankle and left knee to get to the other side of me where there was loads of room, before deciding he preferred the other side after all and went back, forcing me to shuffle over to create space.
But god, nothing hurts as much as when he walks on my boobs!
