Does she drink milk? If not, she could have a riboflavin deficiency. If she is taking prenatal vitamins, she is probably getting folacin, iron and vitamin C only. If she is taking a multivitamin that has 100% of all vitamins and minerals, then I doubt she has a vitamin deficiency. I would recommend your daughter see a dermatologist as well as she may have an infection which should be treated even if she is pregnant.
My daughter is 7 months pregnant and the corners of her mouth are so cracked that the skin is growing back crooked. I’m concerned that she has a vitamin deficiency, although she takes vitamins. Any advice or a cream that will help her? Thank you.
