our angel leans her head up on stuff too
what a cute picture! our Angel does the same thing sometimes in different spots. she practically had her face stuck up againt the dining room table leg one time. i thought she was trying to suffocate herself. but no, she was good. i think they love that pressure on their body. at least they know nothing's going to sneak up on them from THAT side.
they're so lucky they have such flexible spines, too!
