The amount of breastmilk an infant can suck in one mouthful is not a fixed value. At birth, the infant’s ability to suckle is poor and breastmilk is not sufficient, so the amount of breastmilk in one mouthful may only be about 1mL. As the baby gets older, the breastmilk becomes more plentiful and the baby’s sucking power increases, so the baby may be able to suck about 2mL of breastmilk per mouthful. Older babies may be able to suck about 3mL of breastmilk in one gulp. Therefore, there is great variability in an infant’s ability to swallow milk, with the average value being around 2-3mL. In addition to the infant’s age, weight, and developmental status, the infant’s ability to suckle is also limited by the condition of the breastmilk itself. Because some mothers’ breast milk is very sufficient and relatively urgent, infants may be able to suck a lot in one gulp, while some mothers’ breast milk is not very sufficient, so they cannot suck a lot in one gulp, and there is a great deal of variability. For breastfed babies, sucking breastmilk is on-demand feeding, don’t be particular to limit the time or number of times, as long as the baby has the demand, you should provide breastmilk to the baby. Breastmilk is the best source of nutrients for infants, so breastfeeding is recommended. It is best to exclusively breastfeed infants up to 6 months of age, and try to breastfeed infants up to 1 year of age. Therefore, if you can breastfeed your baby, try to exclusively breastfeed your baby, no matter how much breast milk you can get in one gulp. In addition to providing the nutritional needs of infants, it can also provide some special immune substances to enhance the immunity of infants, and it can also enhance the bond between mother and child, and it is also very convenient and economical.
