If possible try to get treatment for child. I am 42 with a Port Wine stain on the right side of my face and still live with being teased and called strwberry face in second grade. My mom also tried makeup at a youg age and what a mess that was. I am still embarrased of my face and it is hard to go swimming in the summer.
So please for your child do something and save them from the heartache it causes.
