I just finally got a wrap (Wrapsody Bali Baby Stretch) and we are loving it! I shied away from wraps because they looked so difficult, but got frustrated with our other options and it is working great. Just got it on Thursday, we are now on a weekend trip for a wedding, he was able to nap in it in the airport (nice to keep him on going through security), on the plane, at the wedding, etc. They made me take him out of it for takeoff (because having a baby loose in your arms is safer than strapped to your body, apparently
) but I just pulled the wrap down to his butt and he didn't wake up. It is the first carrier we've tried that he doesn't even seem to notice that he's being put into, just pull it up over him while he is in burp position, like a blanket. So easy to pop him in and out for nursing and diaper changes / EC opportunities.
Our mei tai is also working pretty well, I like it for longer walks and DS is pretty comfy in it, but it's just more difficult to deal with when he wants in and out frequently because of the straps, plus I can't sit down with him in it. We have a Mei Tai Baby which is great, the bottom cinches up so he can have legs out (he only tolerates froggied legs in the wrap), and it has the Zippy panels so we can change the look.
Not so much luck with the ring slings...beforehand I thought this would be the carrier of choice, being able to nurse in it and pop him in and out, but it hasn't worked out that way. He tolerates nursing in it in cradle position if he is really hungry, but that is it. Doesn't like cradle position, doesn't like legs froggied, and he is not big enough to have his legs out for tummy-to-tummy (not enough of the sling under him to hold him securely). It was worse with my first RS, the design just didn't work for us, I got different ones which are much better but I think these will have to wait until he is a little bigger. I hope he does end up liking it because I also got a solarveil one to take him in the shower with me.
I think he will really like a high back carry in the Mei Tai, but I'm a little scared to try it until he can hold his head up, even though I have a padded headrest for it.
