Anyone know of what (ideally side by side) double pushchairs also work with baby seat/carriers? We've had a city mini double in the past but there was a 2 year age gap so only one baby carrier needed. looking at the baby jogger website for example it only every shows one maxi cosi attached. likewise many other seats only seem to show one. For school runs its always been easier to drop them straight onto the chassis rather than swapping over.
