I think most of the time, the moby would still work well. I have a almost 3 year old, a 5 year old and a 6 month old. I LOVED the moby this time. He would nurse and then I would put him on and just wear him for hours till he had to nurse again. It was a very safe place for him to be with the others running around and needing help with everything. for quick quick things, the ring sling was my favorite. I always felt I needed to stabilize his head still with one arm though, so I only had 1 hand to help the others.
Good luck and congrats!!!
With our newbie (we have a 3 y/o) we've been using either the kinderpack (infant/standard size) or our babyhawk. We have a moby that we loved with the 3 y/o but have found we really haven't liked using it with the newbie--feels like it takes too long to get on and the 3 y/o doesn't make it any easier. All in all, I use the kinderpack more often because of the hood (keeps the riff raff out...it covers enough that "nice" folk who want to touch/look at the baby can't)--it fits from birth if you get the infant size. The hood is also great b/c we are outside w/ big boy so much that sun protection is pretty essential...
K'Tan and Moby were my favorite and make organic ones. Please remember for the first 6 months or so, you tuck their legs in froggy style...do NOT let them hang out. It's awful for their bone growth and circulatory system formation, and it's unsafe in general.
And I always recommend a babywearing workshop with a certified babywearing expert. It's usually inexpensive, and well worth it (at any price).
Once the baby's legs rest at a 90-degree angle, it's fine. But if the legs are just hanging down, it's bad.
Happy to help! (Esp since I see too many newborns out there with their dangling, unsupported legs!) There are a lot of links to support it, but here is one. This helps explain why...
Additionally, from another forum: "Dangling legs is not recommended because it encourages hip dysplasia, hollow back and the weight tends to be on the pelvis rather than the bottom. The best position for carrying is with spread legs and knees higher than hips (in an M shape), which aids correct hip positioning and supports the rounded back. Ossification (cartilage becoming bone) of the pelvis and hip is usually finished by about 9 months, so proper support with legs spread and knees higher than hips is important until then. Support for the rounded spine is needed until 6-9 months when awake and up until 1 year when asleep as the muscles relax."
Personally, my son was huge pretty quickly, so his legs startled falling at a 90-degree angle instead of dangling at just 5 months. But, since he was still comfy in froggy, I kept him in that. Once it started to change and feel bulkier to me, I switched him to legs out and our timing happened to be great for that.
Hope this helps!
