I want to get more into Baby Wearing but have no idea what's what, apart from the basics. There are a zillion wraps and carriers out there. How would I know what to use? I currently have a Beco Butterfly 2, which I love and use all the time (but only front carry cause I need more back carry practice) and a Sleepywrap which I'll retire until I have another bub, since mine is 8.5 mo and 9kg now.
