I think I'd go double pram. My daughter is 3 and still needs a pram at times. There's no way at 2 she would have been alright without.
My eldest will be 23 months when May baby arrives. He’s been walking since 12 months and is very confident and can walk quite a distance. We’ve decided to get a buggy board and will use that most of the time with baby in the pram. If we’re going for longer days out then baby will go in a carrier and eldest will have the pram.
i’ve seen people get little add ons to their pram for baby to sit/ stand on. depending on how your little one is!! xx
