I'm a first time mom-to-be so I'm pretty clueless. Do any moms have baby carrier recommendations? Looking at online reviews, I was thinking of going with Ergo baby. I do want it to be as ergonomic as possible since I tend to have back issues. Would you recommend this brand, or any others? Also, does anyone have a recommendation between the Ergo 360 or the original. My initial thought is that I don't really need the 360 because the biggest difference is allowing the baby to face forward, and also it has a lower weight limit. Do you ever carry your baby forward facing and recommend a need for it?
