OK, so I'm a big baby wearer (I don't know how anyone survives having older children and a newborn without a good sling/wrap). I wore both my girls from birth on. The trouble with DS is that he's so tiny. At 7.5 weeks, he's just barely 5lb (which is double his birth weight, so that's big for him, lol). He's so light, the ring slings are hard to adjust the way I like them and they don't sit right. He's so tiny that he slides all over/slumps down in the mei tai and the onbuhimo. I have a snuggli structured carrier, but it's pretty uncomfortable. I didn't like the moby with the girls, but maybe that would work better for someone so tiny? Am I missing a technique for the ring sling (my favorite carrier) or the Asian style carriers (my 2nd fav). Any suggestions for preemie wearing?
