I know there are earlier ones, but the first one that popped into my head was when my son was about a year, and starting to walk by pushing this toy on wheels; early in the morning, before anyone in our
neighbourhood was up, we'd walk
around the block, me in my pjs with a mug of tea, the rising sun shining on his bright little
face, as he plodded that LONG distance (for his little strides) beside me.
