Please forgive the potential ridiculousness of this question.

For those who've used dummies.....Can you give baby a dummy from time to time during the day only, or is it all or nothing? If they take a dummy sometimes will it become necessary all the time, at night and for naps?

I'm toying with the idea, mostly because I think dummies are super cute - but dd2 settles well without one and can get herself back to sleep (currently anyway, I'm well aware suddenly baby sleep can change), so I don't want to create a sleep prop for the sake of giving her a dummy from time to time during the day just because I think they're cute. But they are cute.
