Babies who still have jaundice on the face after one month should undergo further examination to determine whether the jaundice value is particularly high. If the value of jaundice is seriously over the standard, it is best to carry out systematic examination and targeted treatment. If the jaundice is only mildly or moderately elevated, it can be restored to the normal state through dietary modification or blue light irradiation and other therapeutic means. In general, you can let infants consume more vitamin-rich foods, such as fruit juice for children to drink, to promote the recovery of liver detoxification ability, which is very good for the mediation of jaundice. In some breastfed babies, the resolution of jaundice can be delayed until two months or longer. The clinical features are that, except for the jaundice which has not subsided, the weight and height of the baby have all grown normally at the end of the month, and the liver function is normal, so no treatment is needed. Mothers can eat more nutritious food, such as eggs, milk, fruits and vegetables, to maintain a wide range of nutrient intake, which is conducive to the growth of milk nutrients, and can promote the child’s jaundice to subside.
