Is this lady normal ?

My "mother" always seem to think that she knows everything.I dont go out much with my son b/c I dont have a car...so since its summer,im trying to take him out so that he doesnt stay bored in the house.She has the nerve to tell me that only hoodlums go to the park .She says stupid things like that very often.Im sick and tired of it.Im saving up to move out and I also help with the bills....She criticizes how I dress my sun,what soap and lotion I use on him,what I feed him etc.Its not like she succeeded in life and knows all the answers.She pisses me off and honestly,I hate her.Ive had enough.I havent called her "mom" in like 2 yrs...help me !
