It's an awkward moment, when the bus driver asks you to fold your pushchair to make for another passenger.
You've boarded a bus with your baby and pushchair in tow, successfully negotiated your way past throngs of other bus passengers, and possibly even worked out how to apply the brake properly and wedge yourself into a vaguely safe spot where you can also check on your sleeping cargo.
Then all of a sudden you're expected to hoist your kid out of his cosy cocoon and work out how in hell to fold the pushchair despite never having done so since you bought the blasted thing.
Factor in having more than one child with you, and the whole thing turns into a logistical nightmare. Before now I have literally had to hand my weeks-old screaming baby to a total stranger to hold whilst wrestling to collapse my pushchair and trying to prevent my toddler from falling face first into some hostile spectator's lap.
It's bad enough when this happens because you need to make space for another passenger, but would your reaction to these circumstances be any different if you were asked to move for a wheelchair user?
Earlier this month, a man was granted permission to take his case about access for wheelchair users on buses to the Supreme Court.
The BBC reports:
Doug Paulley, from Wetherby, was denied access to a FirstGroup bus when a woman with a pushchair refused to move.
Senior judges overturned an earlier ruling which said the firm's wheelchair policy was discriminatory and breached the Equality Act.
He has been granted permission to take the case to the Supreme Court because it raises issues of public importance.
The man was unable to board a bus because a woman with a sleeping child in a pushchair refused to move when asked to do so by the driver, despite a sign on display which asked passengers to give up the space if needed for a wheelchair user.
Speaking personally, I'd happily move to create space for a wheelchair user on a bus, on the basis that I see their need as greater than mine. Yes, it's inconvenient to wake a sleeping baby and fold an unwieldy pushchair but I have the ability to do so, so why wouldn't I?
But not everyone agrees. One of the Playpennies team has this to say on the subject:
"I didn't mind folding up the buggy when my children were older but to me it's wrong to favour a wheelchair user when someone has a toddler and a newborn baby on a bus. I would stand and wait patiently for bus after bus to pass until one had a space for us - we relied on buses. Whoever is first on the bus, is first on the bus, in my view. You shouldn't have to move unless the child is old enough to sit on your knee."
