I found
this one last summer when DS was a year old and not walking and I still wore him sometimes upto 75% of the day. It has decreased since he decided to walk finally at 17 months and I was really struggling with my back at the time. We still get it out now from time to time, on his rough days, and he's over 30 pounds. I loved it because he wasn't all out front but fit on my hip snugly.
