Some mothers will judge whether the nutrition is good or not by the color of breast milk. When they see that the color of milk is very light and thin, they think it is &”;no nutrition&”;. In fact, this is a wrong understanding. Because milk is divided into pre-milk and post-milk, the concentration, color and composition of the two are different. Pre-milk: it is light blue, rich in minerals and immune factors, and has a high water content, which can quench thirst, so babies who are exclusively breastfed usually do not need to drink extra water before 6 months. Post-milk: pale yellow, rich in fat and lactose, high in calories and hungry, which is the key to baby&;s weight gain. Some novice mothers let their babies suck on the other side before eating empty because of their lack of experience, so that their children can&;t eat post-milk, and their fat intake is insufficient, so they are not full and their weight gain is not ideal. How to judge whether mother&;s milk is nutritious enough? It can be observed from the performance of the baby after breastfeeding. For example, if the baby of 2 months can sleep for 4 ~ 5 hours without crying or making trouble after breastfeeding, it means that the quality of the mother&;s milk is good; If you wake up hungry less than 2 hours after eating milk, it may be that the mother&;s milk is thin, or the milk is insufficient and the child is not full. In the former case, mothers can improve the content of protein and fat in milk by adjusting their diet structure, such as eating more milk, soybeans and bean products, fish, chicken, eggs, lean meat and other foods, which are rich in high-quality protein and unsaturated fatty acids, but at the same time, they should also pay attention to balanced nutrition, and all kinds of fresh vegetables and fruits should be eaten in moderation to supplement vitamins and dietary fiber to prevent constipation. One of the main reasons for the latter situation is that novice mothers will not judge whether their babies are full or not. In fact, to judg——, listen, see and measure. In the case of sufficient breast milk, the baby will take 2~3 times, and then swallow a big mouthful of milk, so that it can be full in about 15 minutes; If the baby sucks for a long time but doesn&;t swallow, or the frequency of swallowing is too low, it means that the mother has insufficient milk, and the baby is struggling but can&;t eat much milk. Newborns who eat breast milk should urinate 6~8 times a day. If the baby&;s urine volume is found to be less, it means that the baby may not be full. Quantity: Does the weight increase or decrease? In the first month after birth, the baby&;s weight can increase by 720~750 grams, and in the second month, it will increase by about 600 grams. Parents can weigh their baby every 4 weeks, record it and draw a &”;weight gain curve&”;. If the baby&;s weight gain is normal and the curve rises steadily, it means that the milk is sufficient and properly fed. If the weight gain is not obvious or even reduced, it is necessary to find the reason, either improper feeding or the baby&;s digestive and absorption function is out of order.
