Re: At what age/ weight did you stop wearing your baby?
^ I agree with the above.
My son is 2 1/2 and we still wear him occasionally. Actually, I went to Target a few hours ago and he requested that he go on my back rather than ride in the cart. Our Ergo has gotten tons of use and is one of my favorite baby items (and now I have a 4 month old as well, so it will continue to be used for a long time).
But it sounds like yours haven't been very useful to you to begin with, so it won't be much of a loss to sell them. If you change your mind later you can always get a different one, or find a carrier that is more suited to you that would get more use.
