Under normal circumstances, after the baby has been vaccinated, the mother can eat seaweed while breastfeeding. Kelp itself is an ingredient with high nutritional value. Consumption of kelp during breastfeeding can improve the resistance of the mother and the baby, and to a certain extent, can also prevent anemia, rickets and cretinism and other diseases. The rich calcium content in kelp can also effectively help breastfeeding mothers prevent osteoporosis, high blood pressure and edema. However, it is not recommended to consume large quantities of kelp for a long period of time, as it can lead to excessive intake of iodine, which can be passed on to the fetus through breast milk, and may lead to dysfunction of the baby’s thyroid gland.
