AIBU to moan about someone who keeps moving my pushchair?

[BedHeadTigi]

I live in a block of flats which have 4 floors, and i live on the second floor. So to make my life easy i leave my pushchair downstairs in the communal hallway, its out of the way as there is an open space round the side of the stairs with storage space under the stairs too. Another neighbour leaves her pushchair there too, but mine is not in the way so no one need move it, but someone keeps moving my pushchair. I hope i dont sound like im moaning about something that seems so trivial but it is really bugging me as i dont touch or move around others peoples stuff, so why is my stuff being moved about when its not necessary. Should i carry on leaving it in the hallway or bring it up to my flat where i know its safe? What would you do?

How old is the child that needs to go in the pushchair? If under a year, put him/her in a sling. Then you don't have to use the pushchair every time you go out. (goes a bit misty-eyed for the days when DC fitted in a sling and I didn't have to deal with push-chair rage.)

anything you can lock your pc to? Maybe ask the other mum if hers gets moved - she might know something or if she has some issue it gives her the opportunity to speak to you
