I have vitiligo since 1.5yrs, I have been using some creams to cure it from 3months. Now I am 2months pregnant, how can I avoid vitiligo to the baby in my womb?

Your concerns regarding your condition should be discussed with your doctor, but vitiligo is hereditary; some children will inherit it, some won't. There is nothing you can to circumvent this condition in the womb. However, they do warn against strong creams being used while breastfeeding.
