When using a walker, it is the walker in control of the baby’s body weight, so it does not allow the baby to achieve the desired motor learning effect. Secondly, the baby’s bones have less calcium, soft bones, easy to deform, lower limb muscles and keep the arch of the muscle group development is not complete, the march of the walker is gliding, the speed is very fast, the baby may not be able to afford, very easy to cause deformation of the baby’s spine and lower limbs. Third, the toddler is not safe, it is easy because the baby’s center of gravity tilted over, or quickly slide to a place invisible to mom and dad, causing danger.
