The Oldest (Batfamily Fanfic)

Before Batman, there was Andrew Wayne.
Bruce's first son. A child born unable to speak, who learned to communicate through signs, actions and the quiet bond he shared with his father. For years, Andrew was Bruce's whole world-the one person who knew him before the mask, before Gotham, before the mission.
But as the Wayne family grows, Andrew slowly finds himself pushed into the background. Dick Grayson, Jason Todd and others each bring new needs that Bruce tries to answer, while Andrew remains the son who never asks for anything.
Brilliant, disciplined and impossibly resilient, Andrew hides a lifetime of exhaustion behind a quiet smile. His chronic insomnia takes more and more from him, yet he continues to train, study and endure without complaint.
Because Andrew has always understood everyone else.
The problem is that no one realizes he needs to be understood too.
A story about a son who never stopped loving his father, even when he started wondering if his father still saw him.
