Cocoon, I have a double jogging stroller, and I received it for free. No one wanted it as it was too big to put into a car/van....I LOVE my double jogging stroller. BUT....I do have to admit, the jogging stroller is amazing as it has the big tires to push through the snow.
I guess the question you have to ask yourself....how many little ones are you wanting in your Home Daycare? I have 2 little ones....they still are uncertain with their snowsuits/boots on.
If I had the funds, I'd buy the triple! But I bought myself a used choo choo wagon. I know it won't work in the snow, but there's no snow here, so it's been a good purchase!
