When did you decide you were ready to have a baby?

My husband and I got married 9 months ago and always think and talk about having a baby. But everyone around us tell us to enjoy married life and life without kids. We're both 25. We really want to have a baby but we don't want to regret it. 
What do you think? When did you finally know you were? How does it feel like to be ready?
