I can't remember when kids start to get moles. My 3 year old has a large mole in her hairline, I think it started when she was about 6 months and it is now about the size of a 5 pence piece. I'm not worried about it but it is quite big so I'm glad it is covered by hair (just). It's the only mole she has. My twin boys are now 9 months and haven't got any freckles or moles. Does this mean that they are unlikely to get any large moles? I know it's vain, but I really don't want any large moles on their face.
