The two year-old was born with the marks on his back and he has to be checked over by doctors every three months in case it turns tumorous. Mum Stephanie Brown, 34, says Oliver is likely to face tough times as he learns to live with the condition. The mother-of-two, from Fenstanton, Cambs., said: "He is one of the fortunate ones, some children are riddled with moles and even get them on their eyelids. He actually has his on the top half of his back so it looks like wings. There can be lots of questions because it comes up to the nape of his neck and so is visible. As he gets older we would hope he can accept himself for who he is." Oliver was diagnosed with Congenital Melanocytic Naevi (CMN) - moles or birthmarks which are present at birth and usually oversized.
