My 4 year old and attitude

Have you ever felt you have a teenager to take care of and yet realise its been only 4 years since you had your child...is it just me or a whole lot of people who are at the receiving end of "attitude" and a preschoolar who does not understand the rule "My roof, my rules". Every "selective hearing" episode is followed only by my blood pressure shooting thru that roof i own and my kid lookin at me like a Drama Queen and having no clue wat i'm upset about. Does anyone have any idea to have a preschoolar and still feel like having a preschoolar living with you?????
