1) Stretchy Wrap (Similar to a Moby)
The wrap I have was made by a WAHM (work at home mama) who is no longer in business, so although I love mine, I cannot link you to it. Basically, they are a very long piece of stretchy material that you wrap in different ways to create the carrier. It can have a learning curve and some folks never get the hang of the wrapping part but after a few YouTube videos and some practice I found it to be a breeze. The most popular of these types of wraps is the Moby which is sold at most of the major baby retailers. There is also one called the Baby K'Tan which I've heard great things about too. The K'Tan is sewn so that it doesn't have to be wrapped as extensively. There are also lots of tutorials out there for making your own. I will say that my friend had one made and the material she chose was a lot looser than mine meaning it wasn't as supportive. So keep that in mind when looking for material.
Advantages: This type of wrap is perfect for those little squishy babies. It snuggles them into your chest and is a perfect place/position to sleep in. I would wrap the fabric before I left the house so all I had to do was pop her in and out at each stop. Finally, carrying Turtle so close to me detered random people from wanting to touch her. Major score during cold and flu season!
Disadvantages: Turtle was a winter baby, so it wasn't a big deal for us, but I've heard that these types of wraps, especially the Moby brand can be very warm in hot weather. These carriers are NOT sutable for back carries, because of the stretch in the material. Finally, because of the length of the fabric, it can be a challenge to wrap it on the go without it dangling in a dirty parking lot. Again, though, I just wrapped it before I left the house and wore it all day long.
Bottom Line: This is my absolute favorite type of carrier for little squishy babies.
2) Woven Wraps
Advantages: Front carries, hip carries, back carries the options are endless with this type of wrap. It can be used with tiny squishies up to toddlers.
Disadvantages: The wrapping can be intimidating, although there are many, many YouTube videos out there to help. I wish I'd know about our local babywearing group. I might have found someone who could have helped me figure it out.
Bottom line: If you can overcome the intimidation factor and master the wrapping, this type of carrier is fantastic and can last you a long, long time.
