Well yes I do have a stroller. A few actually. I love wearing my babies but there are times for strollers too for me. I had 3 babies with 1 1/2 years so I couldn't sling them all - although I have tried this on occasion.
First off we (dh and I) are big on going for jogs/runs for exercise. We have a single and a double jogging stroller for this use.
Also when I go out by myself with my 3 babies (which is often) I need the help of stroller. I can either sling 2 and put one in stroller or sling one and put 2 in stroller. My 2 1/2 yo obviously can walk but he usually likes to run (very fast) and sometimes I need him attached to me (holding him or in sling)for safety or strapped in stroller if I'm wearing the twins.
So let's see...with this being your first right? Would you need a stroller...well when I just had my ds I would use stroller for shopping trips. Not so much grocery shopping. But more like xmas shopping. Going from store to store and then accumulating lots of packages that I either had to carry or shove in stroller. Other option is if you are going shopping for yourself. It's pretty hard to try on nursing bras while wearing your baby. And before he was standing I didn't always want to put him on the floor - depending on how clean the floor was and if he was in his suck on everything phase.
Also I am large busted and nursing made them even bigger
. So if it was a long trip out there were times where I just needed to walk around without any extra weight.
But all in all I loved just being able to plop him (them) in the sling and go. So easy and we all loved it - me and my kids and I even got dh doing it.
