So hoping for some advice. The baby carrier I want doesn't have much arm room for the baby and only allows the baby to have their arms one direction. My husband's grandma got me a baby bjorn but, I've used them before and they don't have enough lower back support for me. So I'm trying to decide should I get the one that I originally liked that's 40 bucks or go for the 70 dollar one that has much more arm room for the baby? From reviews both have good back support for me. What does everyone think? Pics in the comments.
