I asked Mateo to hang up his towel after his bath. I wanted to see what he would do. He went over and lifted it up to try to put it on the hook and obviously couldn't reach it. He went and got a chair to do it. He's pretty smart. I didn't say anything the whole time and just let home figure it out. I was pretty impressed he didn't just stand there and cry because he couldn't reach, but figured out a solution. Good boy!
