How to be the best dad?

Last week, we welcomed our very first baby. We named her “Agatha”. She is so beautiful and adorable. She’s been my stress reliever every time I get home from work.
Meanwhile, my wife has been very remarkable with her duty in taking care for our child. I always see her tired and I thought it’s just normal for her as a mother.
But now, I’m thinking about taking care for Agatha some time if I don’t have work, also giving my wife a time to relax. Now the main concern is how to be the best dad for our baby.

Please tell me!
