Fetal fat on the skin try not to wipe off, usually 24-48 hours later will be naturally absorbed. However, if the fetal fat on the perineum of the female fetus is too thick, it is recommended to gently wipe it in one direction 5-6 times with flowing warm water and a moist, soft cotton cloth, without exerting force, so as not to damage the baby’s skin. If the fetal fat in the skin folds is not absorbed for a long time, you can use olive oil, emollient oil or paraffin oil to soften and dissolve the fetal fat before bathing the baby, and then wash with normal baby shower gel, which can remove the residual fetal fat.
