I have observed that my son is developing a habit around the things he is explicitly told not to do. For example, despite the childproofing, he has figured out how to pull the lid off the sockets, and he knows fully well that he should be taking them off. We explained to him that there are dangerous consequences to putting fingers in sockets, and he seems to understand the premise, however, just to tease us, he will go close to the socket and pretend to take it off. I really don't get why is he behaving this way. We are a very involved family and he gets plenty of attention. He is very social too, has his own friends, etc. But just weird at home around us two.
