I got a a [name]Moby[/name], a HotSling, and a [name]Baby[/name] [name]Bjorn[/name] as gifts. I found the [name]Moby[/name] to be the most convenient one when my daughter was newborn (<6 months). It takes a few tries to get the hang of putting it on, but after that it’s pretty easy. Moby looks cool and the baby feels very secure against your body. The only drawback is that they are very warm to wear.
Baby Bjorn was our favorite from 6 to 12 months. It’s a snap to put on and allows the baby a lot of freedom to move and look around. It also is more “gender neutral” looking so my husband felt comfortable wearing it too. We loved the BB.
The HotSling was a hot mess! Even though it came with a DVD to show you how to use it, I never did seem to quite get it right and no matter what arrangement we used, it was uncomfortable and slipped around a lot.
Just my experience, but I hope it helps!
