Don't worry about this. If you are breast-feeding, you will not get fat as long as you strengthen your exercise and eat on time, and it is best to eat less and more meals, and keep the principle of matching meat and vegetables. Moreover, as the baby gets older, the more milk you have, the weight will gradually decrease, and then it will decrease in a few days after weaning, because you won't want to eat too much in those days, so wait until the end of lactation. The most important thing is that the baby can eat the healthiest milk.
I am breastfeeding now, and my sister has given birth to two babies. That's what she told me when I was worried about losing weight. I'm really thin now, from 140J before I was born to 1 10J now. The baby won't breastfeed until next spring, so I think it will be 98-65438 after weaning.
