Ok I don't know if this exists but I'm hoping someone will know of them or something similar, DS will be 2 in July just after DC 2 is born, and was hoping someone has heard of something like a scooter that can attach and detach from a buggy onto the side, so that he can either scoot along himself or stand on the scooter while I push the buggy, using it more as a side buggy board? Anyone?
