Daredevil

I'm starting to get a little worried.  My son has only just started to take his first tentative steps (a late bloomer in that regard).  He has for some time, however, been working on various other stunts and acrobatics.  Mostly climbing.

For a couple of months now he has been able to climb up and down from the couch pretty gracefully.  Once he got bored with that however, he started trying to climb over the arms and back of it.  Then he moved on to the coffee table.  Then it was his "stand and learn" table:

 Instead of "standing and learning" he climbs up on top of it and perches there like a cat.  Now he steps up onto the electric baseboard heater to get up on the window ledge- and he just clings there like spider man. 
Today he started with the chin-ups on the kitchen counter.  He can't get his chin all the way up yet, but he can get both feet off of the floor and then tries to scale the cupboard.  How am I ever going to baby proof my house now?

My friend was telling me the other day about a little guy she knew of the used to balance on the arms of furniture and dangle from ceiling fans.  For reals?  I'm terrified.  I've had a hard enough time keeping up with him on all fours!
