Does anyone know if I can buy just the adapters for the second seat? We have the Apple 2 Pear anniversary edition, we have DD (newborn) in the car seat or the carrycot and it came with a seat which I want to use for DS (toddler) but the pip adapters come with a second seat unit which I don't need at the moment, I'm just needing the kit to make it into a double. Hopefully that makes sense.
