My baby was born fair nd had jaundice. After phototheraphy she became full darker within 1 week of her birth. She has mangolian marks on butt, hands nd legs too. Me and my husband are white complexion. Its being 15 months we have seen little change in her face but body skin colour is very slow in developing colour. Mangolian marks have become so dark.
Welcome to Chat Doctor. It is natural for parents to be concerned about the well-being of their child Chat Doctor.  Mongolian spots are very common in Asian, African and Hispanic populations. Usually these are black/bluish spots in the sacral area, however, this is usually a benign condition and stays there for a long time. It mostly disappears when the child reaches his/her tenth birthday. I would recommend you to visit your children pediatrician for a well-baby check up and to update her/his vaccination. The doctor can confirm whether these are Mongolian spots and will document it in the file for future reference. Thank you for giving us the opportunity to help you. Please feel free to ask if you have any other questions.
