My 2+ year old is obsessed with band-aids. Every owie needs one, regardless of blood. This wouldn't be a problem, but when they start to fall she gets super upset, especially if she's tired. Why do they always seem to fall off at bedtime? I've tried telling her that band-aids are just for bloody owies, but she's adamant. Should I just go with it? Any other band-aid maniacs out there?
