...stop bringing/renting a stroller for your kids? I know every child is different and I'm not looking for any criticism towards those that used them with older children. I'm just really curious to know when I can reasonably expect to be rid of the hassle of bringing strollers on airplanes,bus,etc. Last trip we lugged 2 full size strollers out of necessity. This summer I'm returning with my older kids only so I'll be stroller free, but I'll probably take the younger ones back within a year or so. Thanks for your input.
