Is it normal my mom is like this with my little brother?
Whenever she is helping him with his homework she always yells and says things like "Do you know your friends are smarter than you" or "Are you stupid?" and "Do you think you can read good?" and if he says yes she will say "No you are not!Because your friends can read better than you"
So I usually help him with his homework when I have time.I even remember her doing this to me when I was younger so Ive never asked her for help with anything when I was able to start doing this for my self.
By the way he is 7 years old.
