Lots of breastfeeding milk and hubby can suckle. Milk is rich in fatty acids, vitamins, proteins, and carbohydrates, which are nutritious and easily digested and absorbed. There is a lot of milk during breastfeeding, so your husband can suck it, and adults will have no problem eating the milk. Husbands can also help relieve breast milk stagnation by expelling the milk after sucking. If an adult suckles the nipple, it is important to wash the breast and nipple carefully before giving milk to the baby later in life. Because the adult oral cavity may come into contact with some pathogens, coupled with some people also smoke and drink alcohol and other bad habits, sucking after the surface of the nipple may be residual pathogens. If they are not cleaned, there may be a risk of cross-infection if the child suckles directly.
