A.S.
I don't want to alarm you, but my niece has trichotillomania. Her mom and dad noticed it when she was pretty young and by the time she was around 2 or 3 she had a bald spot on the crown of her head. At first they thought it was a behavior she could control but finally found some help and she was diagnosed. It's compulsive and she can't help it. My sister-in-law notices it most when her daughter is bored and sitting still or when she is falling asleep. They have another daughter and have noticed her pulling her hair a little too. Because they were aware of the disorder they noticed it in her even younger. I would at least find a doctor that would listen to me and not tell me not to worry about it. If you are concerned, then it's worth getting a better answer. Good luck.
