When my baby was first born I was very intrigued with the idea of carrying him on my body so I started experimenting. I inherited several different kinds of carriers; a Nojo sling which I fumbled around with for a while but finally figured out how to use it and we still use it to this day however infrequently, my ds is now almost 20 mths, and a front carrier of some kind that worked great for a while. We tried several others that we didn't like and then turned to the baby bjorn which served it's purpose well for several months. At about six months I just couldn't stand having him hang on my front any more, then it was back on the roller coaster ride of trying to find the right carrier. Now I use about 95% of the time The ERGO. It is amazingly comfortable, versatile and my baby loves it too.
