Changing my position on strollers. If you only have one kid they're pretty worthless, but in a two-kid family in which the offspring are separated by two years or fewer, a double stroller is an absolute necessity for grocery shopping. The firstborn tolerates a ride in the stroller a hell of a lot better than he would a ride in the cart. (For non-parents who fashion themselves in such a situation one day, letting a 2-year-oold walk by himself at a grocery store is about as intelligent as lowering taxes to cut a budget deficit).
Double strollers are wide and unwieldly but they work marvels at preserving sanity. I'd like to use this theoretically public forum to apologize for my previous anti-stroller remarks. I was wrong. So, so wrong.
