Another vote for the Ergo Its great. I can still carry dd(31/2) in it, although she is getting too tall. On my back is still fine. It supports her weight really well - not painful like I found the baby bjorn to be after a while. Wish I'd gotten it sooner - it was really great.

I've never used the infant insert for it, but I did also like the baba sling when my daughter was younger. When she was over 2yrs I still found it handy for a hip carry but it did give me a sore back after a while. She loved being in it when she was a baby. I have seen some really nice patterns in similar slings.

I also went to a baby carrying workshop years ago, so we used to use a piece of material and tie her on when she was a bub. She loved it She's a bit of an 'up' kid
