If a pregnant woman has insufficient milk, it is recommended that she take more supplements, pay attention to rest, and breastfeed more. 1. More supplemental nutrition: If you want to have enough milk, you first need to have sufficient nutrition, eat more fresh vegetables and fruits, and also eat more protein-rich foods. Drink more soup, if the diet is not balanced, it is easy to cause the synthesis of milk is not enough, which will cause the reduction of milk. 2. Pay attention to rest: usually pay attention to more rest, do not stay up late. If you are too tired or not enough sleep, it is easy to affect the secretion of lactogen in the body and lead to insufficient milk. 3. Breastfeeding: The stimulation of sucking on the nipple can reflexively cause milk secretion.
