Yep I second the Ergo... I have both infant inserts, the standard one and the new heart to heart insert... DS was too long for the standard infant insert so the heart to heart worked for us!

I also had a Baba sling, which he loved and was so easy to throw on and get him into, but he has outgrown it!

I tried a HAB for a while but TBH the tying got a bit too much for me, too much hard work!
