How often do you do cupboard inventory?

In the last year I've not really been through my kitchen cupboards.
So I've noticed recently that a few dates on things have expired.

My partner has brought this to my attention as recently he's been going into my cupboards.

During this pregnancy I've not cooked like I used to. Pancakes, cakes, southern fried style chicken haven't been part of my diet. Not like before.
Also out of sight out of mind.
