Mother’s milk is the standard food for babies, and no formula can match the milk produced by a mother’s body. But there are many mothers who worry about not having enough breast milk, so how can you tell if your baby has had enough? How does a mother keep track of her milk supply? How do you know if your baby is full when breastfeeding? The most important indicator of whether breast milk is full or not is whether the baby has normal weight gain and urinates more than 6 times a day. The weight gain in the first month is about 1 kg. The average growth is 30-40 grams per day. If the weight gain is normal, there is nothing to worry about. If the weight gain is not good, it is important to improve the feeding position, which can be summarized as “three stickers”, “three positions” and holding the areola. The baby’s mouth and jaws are close to the mother’s breast; 2. The baby and the mother’s chest are close to the chest; 3. The baby and the mother’s stomach are close to the stomach. Three positions: 1) the mother sits and feeds; 2) the mother lies and feeds (suitable for nighttime), but the mother must not fall asleep to avoid suffocating the baby; 3) the mother holds the baby and feeds (suitable for mothers who gave birth by caesarean section). The baby’s mouth should contain the mother’s nipple and areola for the best sucking. If the weight growth is still unsatisfactory after efforts, you can use an electric breast pump to suck out the breast milk to see how much there is. Generally the baby’s milk volume at this time should be about 500 ml per day, divided into 8 times, each time for 60 ml. If the breast milk is 30 ml each time, you should supplement the formula with 30 ml after each breast milk. Feed mother’s milk first and then formula, using a spoon, so that it will not cause nipple illusion and affect sucking mother’s milk. Breastfeeding regularly during the day will increase breast milk production, and gradually reduce or stop formula feeding as more breast milk is produced. Does my baby need to be fed water to breastfeed? You don’t need to drink water when breastfeeding your baby. Because breast milk secretion automatically regulates the amount of water supplied, even in tropical Africa breastfed babies do not need to drink water. There is also no need to feed water to artificially fed babies. How can I control the amount of milk for my baby? If you can keep feeding your baby once every 3 hours, you can calculate the amount of milk for each feeding. 1~3 months old babies can have 500~750ml of milk per day, divided into 8 times, 60~90ml each time. The amount of milk each baby eats varies and should be decided according to individual circumstances. In general, breastfeeding, which advocates breastfeeding on demand, can automatically regulate the amount of milk and the baby will not gain weight too fast. If artificial feeding, often easy to over degree feeding, so that the baby weight growth is too fast, too fat in infancy, adult susceptible to obesity, hypertension, diabetes and other adult chronic diseases. Therefore, not the fatter the baby the better, the weight growth is appropriate is the best feeding.
