Try a sling meet and see which one suits you best. At that age still I preferred a woven wrap, but we also have a Ergo which was great (others like Manduca, Tula, Connecta, Rose and Rebellion, etc. are also great and I know people who love theirs). As long as it's ergonomic and supports babies hips, not the Baby Bjorn style where they dangle down, and it's comfortable for you, it's a good fit. But there are so many that it's worth trying out a few different kinds if you can before you buy. We also have a Little Life hard structured carrier, which is great for if we are out walking all day. It's very heavy (I can't carry it for any length of time, but my husband loves it). But I can still carry our almost 3 year old in both the Ergo and the woven wrap comfortably, so either style would be great for a 16 month old.
