Hi all, 18w FTM here and no experience with strollers... To complicate things, we don't have a car and don't drive, so will need to rely on public transport (train/tube/bus) to get around with the baby. I'm looking at the different Bugaboo models and can't decide which one is best and easiest to maneuver for public transport? Bugaboo Bee? Would love to hear advices from experiencing mums pls. Thank you!
