If there is a lack of milk, the feeling of bloating is usually not obvious after 24 hours; if there is an abundance of milk, it may take about 5-7 days to inhibit the secretion of milk by artificial bloating. In the process of returning milk, most women will experience bloating and pain. Due to individual differences, the symptoms of returning milk vary from one group of people to another and the time to disappear also varies. Usually on the 5th-6th day of breastfeeding, the milk secretion reaches its peak, which can cause continuous breast fullness and pain, and the pain is especially severe when the milk cannot be completely squeezed out, after which the pain can gradually decrease until it disappears. However, for most women, milk secretion will gradually decrease in about 7 days, and breast pain will be relieved gradually, and milk secretion will stop completely in about 10 days, and swelling and pain will disappear. In addition, if breast swelling and pain are more obvious when weaning, you can squeeze your breasts properly to discharge the milk from your breasts to avoid the accumulation of milk causing acute mastitis.
