Milk that does not come out when squeezed may be caused by blocked milk ducts or milk that is too thick. When the breast ducts are blocked due to milk stagnation and mastitis, the milk is stagnant inside the breasts and forms hard knots, so the milk cannot flow out smoothly, and the milk will come out after squeezing, but it cannot be sucked out. You can apply hot and wet compresses to the breasts, gently pat and massage the breasts, let the baby suck or suck out the breast pump, and mastitis can be treated with antibiotics, such as amoxicillin, under the guidance of the doctor, which may improve the symptom of clogged milk ducts. If you have a poor diet during breastfeeding and often eat foods rich in fat and protein, such as eggs, milk, fish, pig’s trotters, etc., and consume too much and drink too little water, it may lead to sticky milk, which can be squeezed but not sucked out of the milk, so you need to change your bad dietary habits, and drink a lot of water every day, which may improve the symptom. There are many reasons why you may not be able to suck out the milk when you squeeze it, and we recommend that you seek medical attention for serious cases.
