7 to 8 months of age children should practice crawling, holding standing and stepping. The “toddler car” is called a toddler, in fact, can not achieve the purpose of “toddler”. When children learn to walk, only through their own initiative, learning to master the ability to balance the body, if the child relies on the “walker”, will lose the opportunity to master the balance, is not conducive to the control of balance and learning to walk. There is a 5 to 15 months with a walker infant tracking survey results show that commonly used walker infants will sit, will crawl and will walk on average about 1 month later. The study also showed that children who used walkers scored lower on IQ tests than children who did not use walkers. Children learn to recognize objects by touching, grasping, banging, and throwing them, and free exploration helps children’s intelligence develop. Walkers also increase some accidental injuries, such as knocking things over and falling down the stairs. A few children are short and land on their toes because they are in a walker at 7-8 months, resulting in an abnormal posture of walking on their toes and even mistaken for cerebral palsy. Therefore, it is best not to use the walker or use it sparingly.
