How helpful is baby Walker to teach baby how to walk? My daughter cannot stand though she tries to stand-up every time now, so I decided to get Walker for her.

Walkers are a never ending discussion. See advice from KKH: http://www.kkh.com.sg/HealthPedia/Pages/GrowingUpWalking.aspx "Baby walkers do not help babies to walk earlier. In fact, walkers may even delay your baby's movement skill development or discourage him from learning to walk on his own. Most walkers are designed such that babies are not able to see their feet while walking. This can slow down development of movement as they are unable to make mental connection that it is their legs and feet that are moving the walker. Walkers make it too easy for babies to move around. Babies who are in walkers tend to explore and satisfy their curiosity without developing their balance or walking skills. This may lead to slower development of balance and walking skills. Studies have shown that babies who spent 2 hours each day in the walker were more delayed in learning to walk than babies who did not use a walker."
