The Moby made DH cry. Several times. He had so many problems with getting that thing on and getting baby positioned properly. We ended up giving it to Goodwill when DS was a couple of months old, as I wasn't too fond of it either. It made me feel pretty overheated and frumpy to have so many feet of material exuding off of me. :<
After the crying and the frustration, we ended up using a ring-sling, and I have the same sling (yay!!) that we will use with this little one. It's such a great little sling, just simple breathable cotton (not too stretchy) with a big tail to use for a little nursing privacy.
Once DS got a little bigger (around 1 year), I started using the Ergo carrier, and DH got a big backpack from REI. BTW - I hate the backpack; it's so big and unwieldy on my little frame. It's funny how men and women like to baby-wear differently!
I may have to go to our local natural baby and birth store and try out the boba. Good to know that there are other choices out there these days! The ergo was nice, but a mai tai or some other alternative (like the boba) may be nicer; I used to have some annoying pain in my glutes with the ergo as DS got older. I wore him regularly until he was 4, so that probably had something to do with it.
I mean, what are the options for wearing a big (>= 4 yo) kid? Does everyone just end up getting a stroller at that stage? We used to do a 'walk 1 block, get carried 1 block' thing, but it can get tiring pretty quickly.
