There is no specific time limit for how long postpartum breastfeeding will make you thin. Generally speaking, you should actively control your diet after postpartum breastfeeding, and you can slowly return to your pre-pregnancy weight after exercise 1-3 months. However, if you do not actively control your diet and lack exercise after weaning, it is generally difficult to control your pre-pregnancy weight.

Health advice is to ensure a regular diet, balanced nutrition, no overeating and provide adequate breast milk for the baby during lactation. Do not consider losing weight during lactation, and then try to lose weight after weaning. Postpartum breastfeeding time, at least until the baby can accept complementary food other than breast milk, can be fed to 2 years old at the earliest, or even weaned naturally.
