yes, here are a few things you can do.

:eat ONLY white chocolate the whole way through your pregnancy,

:use lots of blonde hairdye as its been suggested that babies can absorb these things through our scalp, and we all know blonde haired babies are very fair.

cover yourself in zinc and sunscreen all the time, even at night as you dont want any of those pesky rays getting through to your baby and getting him tanned

oh yeah, and if you continued to read this and havent yet realised, YES! i am being sarcastic. of course theres nothing you can do to control skin colour. gee, this place just gets weirder and weirder.
