Hi looking for a travel pram - doesn't need to come onto plane but does need to be lightweight - just don't want to take our more expensive one on flights where it'll get knocked about. ideally we want lie flat (for naps on the go with an 8 month old) and the option for parent facing. Want to spend less than £100 ideally, but happy for it to be second hand, and can slightly increase budget if that's unrealistic. Recommendations very welcome!
