I believe in Glenn Doman's stressing the importance of crawling to baby's brain development. And that crawling should be encouraged and that walking will just follow when your baby is ready for it. Aside from that, I find walkers unsafe, especially with my little one who crawls/creeps very fast, i could just imagine her in a walker zooming all over the room. Instead of using a walker for our daughter, we use a push toy (mini grocery cart), we also use Walking Assistant / Walking Wings, it's like a padded vest w/ velcro and snap wrapped around her chest and has adjustable straps on the shoulder part where you can hold her, it's also good for the parent's back, you don't have to lean over to assist them in walking
