Can you buy a buggy board that will attatch to a Phil and Teds Sport? DS5 is due in Sept when DS4 will only just have turned 2yo. He's a great walker really, doesnt like being in pushchair much but is too little to do away with it altogether. A buggy board would be an ideal alternative to using the doubles kit on pushchair once baby is here but cant seem to find any that will state they fit on a P & T's.
