A. hello actually it might be due to some deficiency is specially vitamin d or calcium just right to expose your baby to early morning sunlight and late evening like 4 to 5 o'clock and also make sure about your intake of food and just tried to apply some moisturizer and observe if it continues try consulting a doctor once
