I have found as my baby gets bigger that the Baby Bjorn is getting less and less comfortable. I have been looking for other options but didn't want to spend $100 for something I wasn't sure would be worth it. We don't use the baby carrier on a daily basis but when we do, I want it to be comfortable.
I found this tutorial and decided to make my own Mei Tai. I have heard good things about them and since I have plenty of fabric in my stash I didn't spend anything to make it.
It is equally comfortable on the front and the back for me. My baby seems to prefer to be on the front but isn't upset on the back. I'm surprised how incredibly comfortable it is. I don't feel like one part of my body was holding more weight than the others. I highly recommend this.
