Em as a shortened form works from cradle to senior ages.

Also used in the Netherlands for both boys and girls, pronounced "Eh-m". Short form for names starting with "Em". My brother's name is Em, just as his full first name. This name should be presented as unisex on Behind the Name in my opinion.
I have a friend named Em. It's a Vietnamese name meaning "young" or "young girl." While Em is really more of a Vietnamese term of endearment, it's her actual name, and can be used as one.
