Most babies are weaned by the age of one or one and a half years, because at that time the milk has no nutritional value at all, and the babies have several teeth. When there is little milk, they will bite the nipple with their teeth, and some mothers My nipples are bitten and bleeding. In fact, we can choose to wean the baby, and then suck the excess milk out with a breast pump every day, to avoid the milk clogs the milk ducts, mastitis and other breast diseases.
I don’t think it’s necessary to buy a breast pump in advance. It doesn’t matter when to use it and when to buy it. Moreover, breast pumps are only available after delivery. There is also a shelf life for breast pumps. We only need to buy them in advance. It will be shortened, and it is likely that we will not be able to use it when the baby is weaned, and we have to buy a new one.
