He's 16 months old and he's exhausting me! He fights about everything and thinks it's a game. He laughs as he refuses to lay still so I can clean his bottom. He hits people with his hands and other things because he thinks it's a game. He beats up the 5yo boy next door. He climbs on everything. I found him sitting in the bathroom sink one day. He had climbed up there all on his own. I had to get rid of my table lamps because he kept climbing on the tables and knocking the lamps off. One of the first things he started doing when he got good head control was headbutting everyone. Right now he's chasing Daddy around trying to hit him with a wooden drum stick and just laughing his head off. He's just a nut.
