Bonk!

That's the sound I heard when Z tripped and landed head first on the corner of the bookcase in his room... It didn't break the skin, but I'm surprised that the resulting goose egg didn't--it was instantly HUGE. Poor little bug.

But he was a trooper--we got some ice and his blanket and rocked together for about 10 minutes before he decided he was feeling better (tho not looking better at all) and off chasing Cleo again.
