It all comes from the brain
Walking is an important motor milestone associated with infants' understanding of their bodies in relation to the environment, according to a study conducted by Washington University and led by Natasha Marrus, a child psychiatrist and assistant professor in Psychiatry. They realized that learning to walk is connected with the brain network called the default brain network that operates when the brain seems to be doing nothing. Apparently, this network is crucial in developing one’s own sense of self, and disruptions can be linked to the early diagnosis of autism. 
One of the most challenging steps in the process of learning to walk is controlling top body heaviness. The head is quite large for toddlers' small bodies, and controlling it over the body while moving the legs in a walking pattern is definitely one of the most challenging aspects of learning to walk. This is why some children take longer to walk than others.
No shoes at home
Parents often wonder what the best shoes are for their emerging walkers, and they tend to purchase expensive hard-soled shoes too early. This may sound surprising, but experts recommend no shoes at all as much as possible. The reason for this surprising recommendation is that when the child is learning to crawl, pull himself up, and to cruise around, he has to be able to flex the feet. It's also important to feel the floor underneath, and this is possible only if the child is barefoot or wearing light footwear. 
Just remember your stiffest shoes or your most uncomfortable heels, and you'll grasp how uncomfortable it is for babies to get adventurous in their hard soles, no matter how expensive they might be.
The final stages of learning to walk
The last step in the walking puzzle is figuring out how to lift off only one foot while the other is still on the floor. Your baby will stagger with her arms up as she learns how to keep her balance. To walk, a child will need to contract and relax a lot of muscles; around 200 of them are needed to make a single step. [5, 6]
Most children will walk by the time they're 15 months old . Children shouldn't have inactive periods that are longer than an hour, except when they’re sleeping. Experts recommend that you provide at least half an hour of adult-led outdoor activity every day, either playing in the park, playground, or going for a walk — and as much free play as possible, where a child can freely delve into toys and things around the house — of course, under your supervision. 
Stay away from baby walkers
Stationary activity centers are interesting to babies and generally considered safe, according to the American Academy of Pediatrics. They've been promoted lately as a safer alternative to baby walkers . Push toys are also a good alternative for supervised play-time. They won't help children to walk sooner, but they are much safer than infant walkers. Just make sure you have an eye on your baby all the time.
