I had a Moby D with my DD and it was my all time absolutely favorite and most comfortable carrier ever! The weight distribution on both shoulders with the wide straps was heavenly(not that at that age they are that heavy anyways..lol) and she was just so snug and it was SO beautiful(a gorgeous brocade front)...I loved it so much and cried when I had to put it away
I loved it so much I bought 2 more in "boy" colors for this baby since the other was a more girly pattern. I cannot WAIT to use them!
They were perfect for nursing too, since I have big boobies and she oculd be upright all snuggled and I could just whip a nip into her mouth
I also have an Ergo which I wouldn't use for a newborn even with an insert, it just wouldn't seem supportive enough with the large openings and such.
I have a mei tai which is pretty good, when they are tiny, you can really wrap them up tight in there too
I also got a bunch of the "conventional" carriers with my first(which I promptly sold..lol) and surprisingly got a few more this time around as well from well meaning friends who have seen me with carriers and just don't know what to get..lol. They are just not really functional for me(like the bjorn or the OTHBH or any of the other pack style carriers), I prefer a mama made or something like that that has been tried and tested comfortable and happy by other mamas like myself!
