I bought this carrier, because I had a boy and he outgrew the weight-limit on the other baby carriers by 3 months old. I read a few reviews and decided to give it a try.... so glad I did. I STILL use this carrier on a regular basis for my 30 pound, 2 year old son. He loves riding on my back in the store and it is so much easier than lugging out my 50 pound stroller. I give the designers an A+ on design and functionally.
