zack does what?

he climbs up the stairs!!!!! ahhh!

we have barriers all over the living room. zack is not allowed in the kitchen cause he puts everything in his mouth. he is not allowed in the bathroom, just cause it's the bathroom. now, he is climbing and i have to block off the stairs. i'm glad he's a little explorer but i really have to keep an eye on him. he got stuck in between the playpen and couch the other day. he squeezed his body and couldn't move any farther. he doesn't know how to back up yet.
