Just fyi, and not all that i, we were told very mixed views concerning putting your newborn (<3m) in a papoose carrier like that. On the whateverthebabywillbefine side we had grandma, our slightly condescending because they had a baby almost a whole year earlier friends, and the delivery doctor (who probably doesn't give a shit about babies once they leave the vagina). On the donotriskfuckingupyourbabiesneckuntiltheyhaveneckcontrol side we had our pediatrician, baby physical therapist (there were reasons), and NICU doctors (the reasons). I doubt either way is life or death, but it is one of the 12,420,432 things that new parents wish they knew before their first child and stop giving half a shit about by the third.
