How to address workplace baby syndrome?

I am 18 years old and work at a performing arts center in a new apprenticeship program which puts me as the youngest person in the building. It's a three year commitment but even the interns are 21 or 22. The next closest age to people in my department are in the their mid thirties. A lot of the people around me have 20/30/40 years of experience on top of me and I often get approached with "Oh my daughter/niece/granddaughter is your age." How do I come to terms with myself that I'm always going to be "the baby" at work for years to come?
