Sleep will definitely have an effect on milk secretion. If you don’t get enough sleep and feel tired often, your appetite will decrease and you will eat less, so your milk secretion will be reduced. Therefore, during breastfeeding, try to get enough sleep and keep a relatively calm mood to help the secretion of milk. It is recommended to enhance nutrition during breastfeeding so as to improve the quality and quantity of milk secretion and to feed the baby for normal growth and development, so sleep, emotion and diet have a certain influence on milk secretion.
