Ta Chloe He was born with it so it went wrong probably quite early in his development. I had cholestasis which played havoc with my mineral levels during pregnancy... and even now i have imbalances (thyroid) that mean i could be calcium depleated. If I was unknowingly hyperthyroid whilst pregnant....

BUT I agree, it's probably just one of those things... i'm sure it's just cosmetic and that everything will be fine.
