Recreation in a post apocalypse should be prepared for.
boardgames like chess or monopoly, packs of cards ( great for a bug out bag), musical instruments (I carry a harmonica in BOB) and books can offer some respite from the boredom that is bound to ensue after TV and other electronic entertainments have faded.

Keeping the kids busy just might keep you sane.

Musical instruments like:
Flute – penny whistle
Sewing, crocheting and knitting
