I have a bunch of carriers - dif't seasons in my babies growth and also dif't babies have led me to purchase a few.
I had a Hotsling and my son (who was littler than his sister at birth) loved it for the first few months - but then it outgrew it's usefulness because he wouldn't tolerate being that snuggled in. I had a homemade Mobywrap that my daughter (who was bigger at birth and liked being upright as opposed to cradled) loved - and I loved it too because once she was in - I could really cruise around and get stuff done and she was super snug/secure in it! I like using it around the house better than while out - because it is sort of complicated to get it on without dragging it on the ground. I've kept both because you never know what this little one will like right at first - but these two carriers worked best for me with my newborns.
I also have a Baby Bjorn that someone gave to us - which isn't really my favorite - but for us, it does serve as a transitional carrier before my kiddos fit into the Ergo - which, after my babies are about 5-6 months, becomes my workshorse baby carrier. I love the Ergo, as does my husband. We own two at this point and we've carried our two kids together when they were both smaller, which is a great advantage in un-stroller-friendly China!
I'd love to try a Meitai style carrier this time around - it's on my list of purchases if money becomes available!
I am addicted to carriers - my babies never liked being put down for what seems like the first YEAR of their lives :) - and I like being with them - my favorite is when they are old enough to do the back carry - and then man, watch out! I can cook dinner, do laundry, juggle my older kid's needs, and heck, even juggle! All while carrying my baby at the same time. I also like having them so close to me when we are out and about.
