Re: If your child had stitches in their forehead...
I had them twice as a child, one set in my forehead, one in my eyebrow. I lost hair growth in my eyebrow from them, but not a terrible scar. The one on my forehead could be seen, for years in my youth, but pretty much became invisible in my teens, and you can barely find it now. I had them when I was around 2 and 4 years old.
Also one easy trick, vitamin E oil, straight oil is the best, or bust open the gel pills, put that on, and it really helps to fade even older scars.
Also I never minded my forehead scar, I actually found it kind of cool as a kid, it was one of the few that never bugged me at all.
