I have been enjoying this baby sling. It was super easy to make, folds up small to fit in the diaper bag and makes walks in the park easier! I have a regular baby carrier but never liked it. I just felt hugely pregnant with a bad back when I wore it - though Ed really liked using the carrier. I think it just didn't fit me right but this sling is perfect. I doubt I'll use it long. I can't imagine carrying a toddler in this sling though there are many different ways to wear the sling. I don't think my back could handle much more weight! But for now I am enjoying it!
I used the pattern found here, and also found some good information at this site.
