Diapers, books, snacks, sanitizer…what can’t you live without on the job?
I always pack a small roll of painter’s tape and a mini Sharpie — “my Swiss Army knife” — for on-the-fly labels, date-stamping milk, quick name tags at the park, and temporary fixes. It peels off cleanly most places, but I skip it on delicate fabrics or strollers with fancy finishes.
