Do you know what he didn't like about the sling Ray? Both my boys hated being carried in the cradle position (River especially - you couldn't even HOLD him in that position), so an upright worked best for us...but every bub is different. Keep in mind that a carrier can be useful for a looong time, Si's 6 months and I have him in a carrier a lot, Riv just turned 2, and mum and dad took him onto the Doulos in Geelong recently (a ship that's docked there at the moment) and mum wore him on her back in a carrier! So they can definitely be useful beyond the tiny baby stage.
