Going to the doctors:(

Willow,
I'm glad that your sister is being checked on. Sometimes, there is no found reason for girls to start so young, but you don't know unless you check.

The only long term effect I was advised of from early puberty (provided its not a symptom of another condition) is that sometimes the girls end up being rather 'petite'. I was told that my daughter will probably not reach 5' in height, but that she would be proportioned. This is because puberty also has an effect on the rate of bone plate growth.

It is scary for a child to undergoo any type of testing & I found that talking to my daughter (almost like she was an adult) helped her. After all, it was HER body that all the doctors were discussing.

I'd be interested in knowing what you are told about your sister. I will keep her in my prayers.
