No milk formation can be solved by adjusting the diet, increasing the number of feedings and hot compresses. 1. Adjust the diet: During the breastfeeding period, moderate intake of high-quality protein, vitamins, minerals and fats and other foods, but also can eat foods conducive to breastfeeding, such as pork chop soup and crucian carp soup and so on. Comprehensive and balanced nutrition can not only promote milk secretion, but also improve the quality of milk. 2. Increase the number of feedings: Letting the baby suckle directly on the breast and increasing the number of feedings to the baby can increase lactogen secretion and promote the mammary glands to secrete more milk. 3. Hot compresses: Before breastfeeding, you can apply hot compresses to the breasts or take a hot bath to promote blood circulation in the breasts and accelerate the triggering of milk formation. Avoid the nipple when applying hot compresses to avoid nipple damage and affect breastfeeding. If the above methods are not effective, it is recommended to go to the hospital in time for examination and treatment according to the cause.
