i am 10 yrs old and my cousin is 9. we live in the same state, different towns. we are both girls. the kids in my school, (i'm going into 5th grade) all look older than their ages. they are all in puberty and some of the kids have their periods and have bigger boobs and are at least 5 foot. all the kids in her school (she's going into 4th grade) all look so young and the 5th graders look like 2nd graders and they probably all start puberty in like 6th 7th grade. my cousin does not know responsibility! she thinks she is a baby. i told her she's growing up but she doesn't listen. she still has her baby blanket! i have my period and i am 77 lbs. she didn't even start puberty...58 lbs! she thinks shut up is a bad word. she thinks stupid is a bad word. she doesn't know responsibility! how can i tell her she acts like a 6 yr old! other details please!

thank you!
