Liam has been able to open the doors in our apartment since before he could walk. They are the handle kind, so he doesn't have to be able to twist the knob, he just pulls the handle down, pushes all of his weight into the door, usually falls down, but doesn't care, because he's into whichever room he was trying to get into.

We now have childproof locks to prevent him from entering any room unsupervised! Gross.
