Leg muscle play one of the largest roles in the development of your babies’ body and capability of walking and eventually even running. Walkers aren’t a replacement for traditional learning, they’re merely tools which can help speed up a baby’s development. There is no need to solely rely on a walker to train your baby, however these machines have been proven to greatly increase a child’s capability of walking, running, and eventual ability to play sports or perform dance, gymnastics, and other physical activities with a range of coordination and balance.
