my girl is having this types of white patches. what could it be. please suggest

A. Hello ma’am I think there is some problem with the First Cry app right now the pictures are not visible to us on the panel so I am sorry I will not be able to tell you what it is but I can only tell you sometimes patches are due to deficiency of calcium could be due to dryness or any other issues so just to be more sure and clear about it consult your paediatrician
