Why?!? Sister rant

Brittany
So my sister is ten years older than me (half sister) and has two teenager children. I'm expecting my first. She has decided (since she lives many states away) that she will send me video tips on how to raise my daughter, one a day...umm what? I haven't asked for this advice, hubs and I have come up with out plan of action for raising our daughter and hope to stick to that or mold it when needed after discussing it together. Why does she think she needs to tell me how it is? I know im her "baby" sister, but I'm not a baby, and I'm getting my doctorate in education - my background is in child to adult education! Gah!!!! I want to tell her all this, just don't have the patience to do so without blowing up and I don't feel the greatest so don't want to even do it. I guess I'm going to get a tip a day on how she thinks I should raise my child...gah!!!!!!! Ok, I'm done...I just had to get it out somewhere before I blew up at her, I hate drama, don't want to start it with her when I know she is just trying to be supportive even though it feels like she is telling me what to do...I think im overly hormonal today too, so it's just rubbing me the wrong way
