My son just turned one and he is a prodigious climber. He is a beast of a baby too. He doesn’t even use his legs to climb up onto chairs. He just grabs both edges and pulls himself up using only his arms. It’s beginning to be a problem because he is so quick that if we don’t see him for 20 seconds, he will be up the stairs, climbing the toilet, and IN the sink banging on the mirror. I’m so glad that I keep my straight razors in a separate rack high up off the floor. It is becoming very tiring keeping up with him all day. He’s also starting to walk too so maybe that will tire him out just enough that we can catch our breath.
