Can a 2 month old baby use a 6+ month MAM pacifier?

My baby boy is 2 month old and I mistakenly bought a 6+ month sized MAM pacifier. He seems to like it and sucks on it well. Would it hurt to give him the 'wrong' sized pacifier? Or should I go out to get the 2-6 months old size for him?... show more My baby boy is 2 month old and I mistakenly bought a 6+ month sized MAM pacifier. He seems to like it and sucks on it well.
