I agree you should do the exact same thing. Explain it as best as you can. It's extremely hard to start at an early age. I started when I was age and developed way before any of the other girls and my sister started when she was 9 and she is now 14 and is built like a woman. Just be there as much as you can for her it will definitly help. But it's not un normal to start at an early age, my and my sister were both healthy kids and not over weight we just happened to start young. Now a days I've been hearing it happen alot more.
