I Have ds-7, ds-4, ds-22mos, and dd-5.5mos. I am a user of a stroller, Kelty carrier, and a sling, depending on the situation. Depending on the ages of your baby/ies. My ds#2 was, and still a maniac,
(hugs for #2), He just likes to be free, ykwim. but anyway, ds#3 *loves* his stroller, and dd will only be attached,
: so I like them all, but oh boy, is it a hassle with the stroller, but some times, if ya have enough kids, ya kinda need one. Hope that this helps, And like one of the other posts, you could always sell/trade it if you don't use it.
One more thing, if little one gets bigger, or too heavy for the sling, the kelty carrier is my favorite, I think that it supports kid and mama equally well. Very comfortable.
