We went moby-ergo-tula, and love them all. I really should be done carrying, since he's almost 4 and over 40 lbs now, but I enjoy having my littles safe and close.
Yes! My daughter likes in from time to time. They're 2 years apart, but weigh the same. My problem with him isn't the weight, it's that he's taking to flinging himself about from time to time, and has caused my back to become injured. So, for shorter carries he's fine, but if he's overly excited, or upset by being in the carrier I have to be extra careful
