Only due to the ridiculous, inconstitent deaging mish-mash of New 52, which despite stating that everyone lost a fixed amount, deaged various characters by as little as a year (Damian) up to as much as ten years (Dick). Barbara was either 16 or 20ish when she became Batgirl, placing her in either her early 30s or mid 30s by the end of New Earth continuity.
