I was discussing this with some childless people and they all seemed to think that people with pushchairs using public transport need to fold them up if the kid is not actually sitting in it. They cited people taking the kid out and putting their shopping in it as instances of rude behaviour in which they should've folded it up because if there's not a kid using it it's not a shopping trolley and it should be folded to make room for other passengers. I argued that sometimes a kid will whinge and scream if left in a pushchair that's not moving and that it's often better to let them out to sit on a normal seat or on your lap to keep them happy and entertained and put your shopping in the seat to keep it from tipping over. If the pushchair was folded where would the shopping go and how would you hold onto the chair (which, when folded, has no brake on most models), the shopping AND the kid all while remaining seated or being able to hold onto something? If you have an older toddler and one of those lightweight pushchairs and little to no shopping with you then it's easy to fold. But if your kid isn't old enough to stand up or sit still and you have a few bags with you, what are you supposed to do? I think it's a bit petty and unreasonable to expect parents to either fold it up and then have a horrific journey trying to hold onto everything or deal with an unhappy child who wants to get out of their seat (and undoubtedly get dirty looks for the noise they're making).
So tell me mums, do you always fold your chair if your child gets out of it or do you keep it unfolded with your shopping in/on it?
