Babies crying and struggling while breastfeeding may be caused by factors such as insufficient milk from the mother, overfeeding, or pain in the baby’s mouth. It needs to be judged according to the baby’s state and physical condition and adjusted in time. Common causes and related suggestions are as follows: 1. Improper breastfeeding posture: the mother will breastfeed the baby directly on the baby’s face, resulting in poor breathing, which leads to crying and struggling while breastfeeding, and the mother should learn the breastfeeding posture; 2. Overfeeding: some mothers will habitually think that the baby is not full and continue to breastfeed the baby, resulting in bloating discomfort, which leads to struggling and crying. Mothers should pay attention to controlling the amount of milk fed, and should not let the child be too hungry or too full; 3. Insufficient milk: the flow of breast milk is a burst of outflow, if the mother’s milk is insufficient, the baby will cry and struggle as it is more difficult to suckle. The mother should promote the increase in the amount of breast milk through dietary therapy or milk promotion, massage, etc., or actively look for alternatives to breast milk to meet the child’s growth needs; 4. Oral diseases: babies suffering from mouth ulcers or thrush will cry and struggle when sucking milk because of oral pain. Parents should pay attention to keep the child’s oral hygiene, can apply drugs externally, after meals need to rinse mouth with mouthwash to maintain oral hygiene; 5, nipple deformity: mother’s nipple is too large or too small, the baby can not effectively suck out the milk, the same will also cry, the mother can suck out the breast milk with a breast pump, and then fed to the child. Caution: If the baby cannot be relieved from crying as soon as he/she takes the breast, he/she needs to go to the hospital. The mother should keep track of when the child wants to eat most, regular feeding times and adjust to a comfortable position for the baby.
