My daughter is about to start year 5, she has all the physical symptoms of puberty (first started 12months ago). She's under consultant endocrinology care as referred by the GP who frightened me into thinking something was wrong. Dd has had a bone age X-ray which showed slight raised growth, 3-9months ahead of chronological age. She's 9y3m and 4ft10. Today she had a second ultrasound which showed ovaries had grown but womb lining thin. The radiologist was unable to comment about how far she is off from starting but I'm sure it'll be before Xmas. Dd is fully prepared with a little bag for school but she's terrified about it all. I imagine she's also going to be the first of her peers. I know 8+ is "normal" but 9 seems so young. How truly common is it to start this young? FWIW she's my first and I was 11.5.
