How do I encourage my 14 month old to walk?

Yay, don't worry about it yet. Each child delvops on his/her own time. You can use walking toys that they can hold on too to help encourage them to move will holding on to an object, walk with them by holding their hands. Give it some more time, time before walking is ok as when they get moving there's no stopping them.

First, I would not worry at all.  There are some little yogi exercises you can do to help strengthen the muscles they need to walk and also, some poses/exercises (more like little games/songs) you can do to help teach them the basics around walking, like squatting up and down which strengthens the lower body and teaches them to 'sit down' vs. fall over backwards flat on their backs.  Check out baby yoga books, there's a popular one you'll find, it's great.  The squat one is simple, sit your baby on your leg(while sitting on the floor legs lengthened), bounce three times, say 'up' then let them sit right back down and say 'down', teaches the up/down needed for walking and strengthens the lower body.
