OK, so I am hispanic with dark almost black hair, hubby is blonde/ light brown. My oldest had a fine coat of fuzz "monkey fur" as my mother called it on young kids, she told me I had a "monkey swirl" on my upper back for a long time. My oldest did untill 4 or 5 years. But my youngest DX 2 years ago is almost 8 years old and still has a fine coat "everywhere". A prominent back swirl and a mustache. She is very thin and I remember in school reading about how malnutrition can cause a fine hair growth, I can't remember the term that was used for kids not babies. While we do not eat the best, she is fed and enjoys a great variety of foods. But I wonder if there could be something else going on in the background? Any ideas on what I should look into? Yearly labs are coming up so want to be able to include anytjing that could be insightful.
