I have a valco runabout and put the toddler seat on the front. It's now up to child number 3 and my 3.5yr old still fits in the toddler seat. Handy as you can fold the toddler down when not in use. Only thing is, it doesn't fit through a normal aisle at the supermarket, you have to use the diabled aisle. OUr pram goes outback and DH also runs with it with the kids in it.
