This intimate friend, if the baby leaves his feet outside when walking, has he already formed a "splayed foot"? If there is, it must be corrected as soon as possible. During training, the mother can put her hand under the baby's armpit behind her and let the baby walk along a wide straight line. When walking, pay attention to let the baby's knees always talk forward. When the baby's feet are off the ground, keep their toes on the ground. When they bend their knees and step forward, there is a slight friction between their knees. Practice twice a day, and long-term persistence will be effective. In addition, check the trace elements for the baby, and check regularly if the baby is calcium deficient and supplemented. It is recommended to supplement calcium to the baby first, and at the same time pay attention to supplement cod liver oil, which can promote the absorption of calcium. Usually pay attention to the baby's diet and eat more foods with high calcium content, such as bean products, shrimp skin, egg yolk, sparerib soup, marine fish, kelp, seaweed and other foods. It is suggested that the baby can be massaged from the outside to the inside of the knee, and gradually improved, wishing the baby a healthy growth.
