S.C.
When my children were that age we alternated between a jogging stroller and a step two wagon that had another small wagon attached ( I had three kids). The jogging stroller worked great and much better than some strollers when we were going to fairs ect because it was some times held out in a grassy area. The wagon worked wonderful because the kids liked to ride in in not so babyish and I was able to have other stuff to roll around also like an ice chest with juce boxes and snacks.
