With so many different types (slings, wraps, pouches, etc.) and brands (NoJo, Hotslings, Ellaroo, etc.) of baby carriers, it can be hard to decide which one to buy.
Along for the Ride offers some help with that process. Their website features a carrier comparison chart and a great little section on how to nurse your baby in each type of carrier.
One quick critique - the comparison chart is hardly comprehensive and leaves out quite a few options. The most notable omission? Baby Bjorn (pictured).
