I know there's a baby wearing section somewhere but can't find it. Feel free to move this post if need be.

I've been given a secondhand Slingalong of Mullumbimby sling. I have no idea how to use it as it has no instructions. We've tried to work it out and it just looks like Brock would fall out of it.

He's 6kgs now - would he be too big now to use this?

If anyone can explain how to use it I would be very grateful.
