To be honest Mel, i never had much luck with Archie in the sling.. Looking back it was obviously because of his broken collarbone being pressed on while he was snuggled up in there so i guess i'm not really a big advocate for babywearing yet as i haven't really had a baby who is happy to be worn! I also have a brand new sling in a box that i have only ever tried on because i got really claustrophobic wearing it!! Also, being a summer baby, won't he/she get too hot in a sling? Excuse my ignorance!
