How Did You Know?

My husband and I have been married for almost 3 years now. I feel like the longer we're married, the more I get baby fever 😍! I'm 25, he's 26. This might be a silly question... But how did you know you were ready to start trying for a baby? We've talked about it a lot but we don't quite feel "ready." So many people have told me we will never be fully "ready." So what do I do?!
