I wore Jo Jo in the infantino at the grocery store, and lasted all of 10 minutes before I thought to myself, no way, this is too uncomfortable. Luckily, she rides like a big girl in the cart now, but I’m left to seek out another carrier, one that will work for long periods of time in California. I may default to my Moby wrap, because even at this age it is just so darn comfortable. The problem is that the wrap all around me is hot.
So many people I know have an Ergo, so that will be the one I try next.
Mother of All Things 
ergo worked for me! I would borrow one and try it out first – $$$
I use the Ergo with Penny. She’s about 19lbs and it is still so comfortable. I love it!
I love my ergo!
I LOVE our Ergo, and actually prefer it to the Moby now that she is bigger. She just feels so much more secure in it, and it is comfortable for me to wear.
Another Ergo supporter here. I gave mine away to a friend when I moved (my son was 2 1/2)…but I have a friend here who goes hiking with her 3 1/2 year old (I believe it’s rated up to 45lbs), and still puts him in the Ergo! In my opinion, it’s totally worth the $$$.
I’m a fan of the Ergo if it has the adjustable chest clip. I tried a friend’s mei tei recently and really liked that. Is there a baby wearing group near you?
We have a boba and really like it.
I don’t find the Ergo fits me well at all. A lot of people do like it though. When my middle child was around JoJo’s age we loved back carries in the Kozy mei tai.
