We have many baby carriers. Probably not as many as my friend, R, but still... A Ring Sling, a Bjorn, a Moby wrap, and an Ergo. We also have several strollers (umbrella, basic/carseat holder, jogging, and e3 double). I'm not even gonna get into the number of bikes and unicycles in the garage, but I digress.
The reason we have so many baby wearing devices is because they all serve different purposes. The sling is great for when they are really tiny, it's great because you can easily slip them off into bed when they fall asleep, and it's very compact. The moby has been great from newborn thru now until ?? because it holds the baby so securely and it is SO comfortable. The Bjorn is really quick to put on and off. The ergo is great for heavier kids and wearing the kid like a backpack.
All this is to say... go try to win a moby wrap this week from Nicki's Diapers.
