Recently my family went on vacation to the Rocky Mountains in Colorado. On our first day we went on a hike with our two girls. The eldest is three, and the youngest is almost one. Since we had only one off-road stroller, we placed the baby in the stroller and had the three-year-old walk. We were a few minutes in, and I was wishing the eldest was in the stroller. All she wanted to do was play in the red sand and rocks along the pathway. I kept nudging her to move along telling her there was more to see.
