I am permanently drowning in things to remember - when do the cars need their MOT, what's the expiry date of my DC's passport, when's the dog next due its flea treatment, pay the window cleaner, change the water filter etc etc. I can do it, but it takes up so much energy, I want to have a list I can check AND more importantly, that DP can also check.
How do you organise yourself to remember everything? Lists? Calendar reminders? Is there an app or a book?
Please spam me with your bright ideas, oh collective wisdom of the Mumsnet.
