My two year old grandson has small brown spots on his back above his left shoulder. As of three weeks ago he had 7 he now has nine. His Dr. Told us to let them know if he gets more so we called the office but she is on vacation. The new ones are , one on his neck and one on his hairline. He is very light skinned and we keep him covered in sun block. Should we be worried and will he keep getting them? :
