On the bus with a toddler ?

Hi ladies I just wanted to know how do you do to go places by taking a bus with a toddler? My son is 18 months and I don’t drive so I’ve been thinking about starting to take the bus to go places instead of waiting on his dad to wake up to take me there ( he works nights ) I’d also like to bring a stroller with me if possible, so if you have any tips or recommendations I’d like to read them.
