Looking for recommendations for a double pram/tandem that will fit on public transport for toddler and baby, toddler is tall for her age and is 2.5 stone.. I've been looking at the cosatto whoosh double as the weight for each child is up to 25kg but I'm unsure if this would fit on the bus or metro. I have been trying to get her used to walking but she will just throw herself on the pavement or want picked up, and she is flighty and doesn't like the buggy board.
