A walker comes from the west, which is a means of transportation before a baby can walk. It generally consists of three parts: a chassis frame, an upper seat and a toy music box, and belongs to the toy stroller category. The walker can moderately assist the baby to learn to walk, and the walker with toys also has the function of "entertainment", which is helpful to train the coordination of the baby's limb movements.

under the premise of ensuring safe and correct use, the walker provides a convenient tool for the baby to learn to walk, and also liberates the mother's hands. However, if the walker is not suitable, it will also have a bad influence on the baby's learning to walk.

save effort for the elderly who look after the baby, but don't sit for a long time. But the walker is not very good for the baby. The baby is fixed in the walker, which makes the baby lose the opportunity of big exercise. Large-scale exercise includes climbing, standing, bending, walking, etc., which can strengthen the coordination of various parts of the body. Because it takes strength to learn to walk, children sitting in a walker can slide effortlessly with the help of wheels when they need to move. Without real independent exercise, babies will have abnormal development when they use a walker for a long time: the inner sides of their knees protrude and swell, and their calves withdraw outward. When their knees are close together, their ankles can't be close together, which looks like an "X" shape; Some calves bend outward, and when the ankles are closed (standing at attention), the knee joint can't be close together and is in an "O" shape, which is called "bowlegged". The baby's bones contain more colloid and less calcium, and the bones are soft. However, the walker slides too fast, and the baby has to push forward with both legs. After a long time, it is easy to bend the leg bones to form a round leg. Baby's development has its own laws, which are closely related to the maturity of nerve and muscle development and vision development. As the saying goes, "7 rolls and 8 crawls will walk", and many mothers prepare walkers for their babies early, so that they can sit still and get on the walkers. Mothers think that they can do housework and let their babies learn to walk. Too early or too much or improper use of a walker, which violates the law of infant growth and artificially "helps to walk", will have adverse effects on infant development. For example, a baby who is only 7 months old sits in a walker. Because he is small and his cushion is too high, his feet can't touch the ground completely, so he can only slide on his toes. Over time, the baby will form a foot-less walking posture with the forefoot touching the ground. Many parents use the walker because they think it can ensure the safety of the baby, but the statistical results have shaken people's confidence in the walker. According to the statistics of the Consumer Product Safety Commission of the United States, about 8,8 infants under 15 months are injured every year because of using the walker.
