Yes, sucking can not only promote uterine contraction and involution, but also stimulate mammary gland to secrete milk, especially in the early stage of mastitis caused by no milk or blocked mammary duct. Husband sucking is far more effective than breast pump. However, if it is not enough for the husband to suck in the unit with insufficient milk secretion, you can find a formal institution for breast-feeding massage. Most postpartum rehabilitation centers in maternal and child health hospitals have this kind of postpartum breastfeeding service. In addition, you can take some breastfeeding Chinese medicines and grandma's recipes, such as sweet wine, boiled eggs, pig's foot soup, crucian carp soup, day lily soup and so on. By the way, if there is no milk caused by mastitis, and you can't take traditional Chinese medicine for promoting lactation and prescription for sending milk, then treat mastitis first.
