My daughter had something they call a strawberry on her forehead that got almost that big by the time she was 6 months old. When she went to school you could barely even see it anymore. I hope people don't say stupid stuff to you when you're out and about - they always did to me.
My daughter has one on her face.....so it will 'always' been seen! She loves it, I always tell her it is what makes it her......She is grade 4 this year, and there is NEVER any talk of anything about it. I think she quite likes that it makes her unique. There will be no one else in this world that will be like 'your boy'!
