When I sent my older daughter off to day care, I scrawled her initials on masking tape and stuck these makeshift labels haphazardly on her bottles, thinking that ought to suffice. Oh, how wrong I was. Some of her things never made it home, and those that did were labeled by her caregivers - in black permanent marker. Right on the item. My fault I suppose.
I have learned my lesson well: Label everything yourself. Preferably with cute personalized stickers and tags like the ones from Stuck On You. They have a huge variety of cute, sort of hand-drawn looking icons to adorn the colorful labels, but what I really found interesting was that they've got allergy warning labels, kosher labels--all kinds of ideas that you might not have thought of.
And yes, they really do stick, thwarting the dishwasher, the washing machine, most torturous of all, busy toddler fingers. -Julie
