I have always wondered this too, LOL I hate it when Thalia tunnels too deep. Zeus lays right up against me but the blankets always come to his neck/shoulders, so his head is sticking out (like people, ha ha).
Thalia, though, "digs" and "tunnels" down to our feet. She only stays there for a short while, and then typically will pop out and I'll put her on the comforter and then add a fleece blanket (or two, if it's cold) for her. I think she gets too hot down under too many blankets. I'm much happier with her having her own blankets to sleep under.
