The period of lactation will last until the milk production is fluid, and may occur as long as there is no fluid lactation. A woman will gradually start lactating 1-2 days after delivery. The milk will be small at first and will gradually increase with time. Women should start letting their babies suckle after delivery, which can also promote lactation and reduce the symptoms of milk rises. Generally, if a woman makes a habit of breastfeeding, the milk rises will also disappear after emptying the milk. Women don’t always have symptoms of rising milk when breastfeeding, it usually occurs when there is too much milk accumulation and the baby doesn’t suckle out the milk in time. If the milk is not sucked out in time, there is also a chance that the milk ducts will be blocked and hard lumps will appear, which will make it more difficult for the baby to suckle. It is important to let your baby suckle more during breastfeeding to ensure that the mammary glands are clear and no more milk rises.
