Just buy the Ergo. I know they're expensive but it's so worth it. I've been messing with the Moby wrap for 11 weeks and tried a chicco carrier as well and always had 1 hand supporting him so I've never been able to be hands free. Granted, my son is on the heavy side, but still. Finally with the Ergo I feel like he's very supported and it's comfortable and easy to put on. Plus it goes up to 45 lbs!
You could probably even look on craigslist for one. This is a game changer for me so just wanted to share.

Hope that helps. I started with a baby K'tan bc it's so hot here right now and that was a fail.
