My SO's son is 9 years old. A LOT happens that makes me think... if he was my son he would not be: saying that, getting away with that, or acting that way. And the standard has already been set by my SO that it's not my place to speak up and say something. So... difficult for me because I have to sit by and tolerate the kid.
Without digging into the specific examples, sometimes I wonder if the kid acting/saying things that he does is all because... that's what all kids his age do. Not being a parent myself, it is hard for me to know. And because, per my SO, its not my place to speak up... I am wondering if there are any books out there I could read to help me understand kids and how they are at different age levels. Maybe that would help me deal with his son easier.
