Bring stroller onboard public transportions

Hi all. Im a SHM, my LO is 6mths and has never go out “gaigai” except when he visits the polyclinic and our parents. Due to my hubby work schedule (hes in retail and hence the long working hrs), i stayed at home most of the time. I really wish show my LO the outside world but i think i might be a hinder when outside with a stroller. Especially taking the bus. Does anybody has this thought? Im also afraid i might not be able to handle it alone. May i know how you guys actually do it? Thanks.
