Awww, misscheeky - flattery will get you everywhere!
Babywearing can get some getting used to, if you haven't done it on a regular basis until now.
I can't say much about these african baby carriers, but have heard they are modelled on the Ergo and sound like a bargain.
That said, I am a stickler for what I know is a good brand and good quality design / production, so am quite happy to shell out more money for something like a Manduca / Ergo / Beco (whatever takes your fancy).
Definitely adjust and readjust until it's as comfortable as you can get it, and otherwise if it's still no good then yep, you probably need to try something else - luckily there are heaps of really good options out there now.
If you have any further questions, feel free to PM me and we can swap email details, or as previously suggested check out www.slingbabies.co.nz
