DS loves being in the K'tan, but I really need something more supportive. He is almost 7 months old and about 16 pounds. Which carrier would you go with? DH isn't convinced the cost is worth it, so price is a factor, as well as comfort. Out of the ones I am considering, Craig's list only has a few Ergos and Tula and the prices seem high for used items on Craig's list. There are no baby wearing groups near me, so I can't try any of them. Poll coming. Choices: Ergo, Tula, Boba, Beco, other
ETA: a little more information.
I am petite and live in a hot climate.
