I was talking about this with my MIL because DD2 was a bit on the fluffy side up until about age 2...apparently her eldest DD was so hairy for so long people would stop MIL in the street to comment on it LOL. I don't know how long this went on for but she was a perfectly normal non-hairy looking teenager when I met her. Still, if you're worried about it, mention it at her next check up, just for reassurance.
