My oldest got her period at 12.5 - the doctor said that once they get breast buds and some pubic hairs then the first period will happen in about 2 years. Body odor starts at about that time as well. In our town,in 5th grade they get the development talk with boys and girls separated in gym class. They then get a sample of pads and deodorant for the girls - not sure what the boys get. My youngest is now 12.5 and does not have her period yet but she has friends who got theirs as young as 10. I was 15 when I got mine.
