Staying at home with kids when they're little is a crash course on multi-tasking. It took me a while to get the hang of it, but baby wearing is totally where it's at when they're so little.
1. Sling - This one is my personal favorite because it was so simple to use even I figured it out. Some of my favorite baby memories and pictures involved wearing the sling while our little one was passed out in the nook of it. I also liked that this sling din't take up much space and fit in almost any diaper bag we brought.
2. Baby Bjorn - I liked this for longer walks once the kids gained more neck and trunk strength. Facing them outward was fun for outings and festivals, facing them inwards was great when I really needed them to chill and/or fall asleep. Using this took a bit more style and finesse than the sling.
3. Moby Wrap - My Better Half bought one of these, and I never figured out how to use it. It required more hand-eye coordination than I will ever acquire, but she always made it look easy.
