could this be vitiligo. 3 year old has a discolored white patch

Honorable members of the forum. kindly help.

my daughter had a small rectangular patch which i noticed when she was probably 2 or 3 months old.

It has been growing now it is a little more than an inch.

Now I notice a little 2 mm diameter circle on the inner thigh and a size of a pen point dot on the forehead.

The old patch on her hip I put a torch and looked most of the fine body hair is black.

I am planning to take her to the doctor to get a confirmation and to rule out anything serious.

I did have a couple of dental fillings in my teeth by the time I had my child.

Also my child had sleep issues used to wake up almost 5 times a night till the age of 10 months.

These days I noticed when she runs around and gets tired her heads sweats a lot. If she's tired and goes to bed the pillow gets soaked with sweat.

She is a healthy child who is creative and good memory and very good vocabulary at the age of three.

She is sometimes terrified at small noises and the dark.

I am very worried at the possibility of vitiligo.

please help !!!
