It's relatively
simple to use, you can use it to carry your baby in several different positions, it's not bulky so you can shove it under the stroller or in your
bag, you can use it
as an emergency
diaper pad or pillow, in some positions you can nurse in it, and (most importantly if you have a toddler) it's super-easy to get the baby in and out of it (and in and out and in and out...).
