We have one bathroom upstairs. It is used by the whole family so I have a basket with the kids items in it (baby wipes, nappy bags etc) in a little basket so I can grab them easily when needed.
Do insists on 'hiding' these in the bedroom every single weekday incase anyone 'pops over' as they might see them. 
It's a family bathroom! It's nothing dirty or used , all clean stuff in a basket!
AIBU to be annoyed by this? This is every single day and most evenings I have to hunt around for the basket and it's not there when I need it.
