Each bub likes different things, with DS I only had a baby bjorn and it was very uncomfortable and hurt u back and neck a lot, I also had a bubba moe, but this wasn't that comfortable when having to walk anywhere. When he was older and I could put him on my hip it was easier and I carried him round a lot in Hawaii haha
I just bought an ergo for bub number two as everyone seems to rave about them, I haven't tried it with bub as I'm still pregnant but I have carried DS who is 13kgs for 2 blocks and back and he loved it and it was surprisingly comfortable. He also fell asleep in it!! I'm hoping new bub likes it to.
I have no experience with the wraps but they look good too
