I bought the Hotsling on a whim. I was using the Lamaze baby carrier, but my daughter was quickly outgrowing it. I liked the idea of a sling that is one piece construction with no rings to mess around with.
The hotsling is sized to fit. They have a handy fit guide to determine what size hotsling you take. I ordered a size six. This was the perfect size for baby when I got it in the mail, but I was dissapointed that as my baby got bigger, and I lost more of my pregnancy weight the sling did not fit comfortably on my body.
I also bought the hotsling because it offered a way to nurse baby discretely while out. I was unable to figure out how that was even possible. I carry my baby on my hip, and love the fact that their is leg padding on the hotsling for my daughter, but getting her to nurse from that position is not going to happen.
I enjoy my hotsling, and find that it is very useful in some situations where you do not want to bring a stroller, but if I were to try and wear my baby more frequently I would have to go out and buy another baby Carrier.
