Although I am not a mother, I still know something about my wife's breastfeeding. For mothers whose babies are still in infancy, we suggest that you don't do too much exercise to lose weight, because it will directly affect the baby's feeding problem. Exercise makes the body produce lactic acid, which will penetrate into milk, without affecting the nutritional composition of milk, but it will have a great impact on the taste. If a mother often breastfeeds her baby after exercise, then over time, the baby will get bored with breast milk. Once this happens, the consequences will be very serious.
