I made my own meitai. It's great for one's back, babe can face in or out and be worn front, back or hip (hip isn't great for bad backs though...).

If you want to see the pattern (has a lot of pics in to show one how to use it) PM me an email addy to send it to (it's a Word document )

ETA - thought i'd add, DD is now 15kg+ and is still worn almost daily in the meitai, though always on my back.
