Don't stand there, at the bus stop, with your kids in the stroller, waiting for the bus to come, then approach the bus door and start to remove the kids and fold up the stroller. That will ensure that you get not only dirty looks but some not so nice comments as well. Be all ready to just hop on the bus. The driver 'may' allow your dh to board through the back door with the stroller, but don't expect to be able to board with him. That back door is basically for exit only, but sometimes drivers make exceptions for larger strollers to board.
Have the kids out of the stroller and the stroller folded up, ready to go before the bus comes into view.
When you get on the bus, head to the rear of the bus, if at all possible, and take a spot with the folded up stroller, near that rear exit door...much more room there. DH will most likely have to stand with the folder up stroller and you should be able to find seating close by. If the bus is empty or close to that (many seats available) your dh could sit down, with the folded stroller next to him on the floor. Do NOT try to put the stroller on a seat. Do NOT just stop at the front of the bus with the stroller...people need to be able to get past you!
I have seen guests try to board the bus with children still in the stroller. When the driver told them the stroller must be folded up, their response was 'but my baby is asleep!!' Too bad, take the baby out and fold it up. I've seen guests in line for the bus, with their child still in the stroller, and the stroller full of bags from the shops. Then the bus comes along, the family moves with the line, and it's only when they get to the bus door that they take the child out, and start removing the many bags, and then fold up the stroller. Can you imagine how annoying it is to be behind that family??!
IF you are considerate of others you won't get those nasty looks. Those looks happen when parents want the world to revolve around their needs..and other guests to move aside for them, or to wait for them to board the bus in their own sweet time.
