My son will have just turned 19 months when this baby arrives so we've bought a baby style oyster max 2 tandem in slate grey ❤️ I love it, ds will sit in the lower seat when his legs get tired and the front seat is removable so a car seat can be clipped into it, it can convert to a single for when ds is too big for a pram, and it even has an option for a buggy board at the back x
