I babywear everywhere and own 5 different carriers, but we have a stroller (one of the BIG graco ones some people apparently like to laugh at

because I liked its stability, true one hand fold/unfold, ability to lie completely flat, 3 different reclines, large basket, and 2 cupholders). Up until NOW I only used the stroller for neighborhood walks, but on our Saturdays out (usually all day) DD would get SO fussy and just scream and scream. She's reached an age where she wants to see everything and won't sleep when she's sleepy. Plus I was worried about sun, and there's no real hat solution that will work for her at this age. She is MISERABLE when the sun is in her eyes.
So at the Renaissance Festival last weekend we took the stroller. *sigh* But it was wonderful. She could sit up and see everything, but when she started rubbing her eyes we could lay her flat and pull the giant shade down to block her view and she took all her normal naps. Plus everyone in our group used the giant basket underneath so they didn't have to carry stuff.
I still wish we could have worn her, but the stroller made the whole day so much better. I guess everything has a place. I would never tell a family they had to have one though - that is so ridiculous!
And as for sleeping babies in carriers - if you have a wrap, you can just turn their head sideways and tuck it in - baby is completely supported.
