With baby #2

Did you ever feel like you were going to miss out on certain moments with #1? SO and I are talking about when to start TTC#2, and one reason in not ready is because I don't want to miss out anything with #1. Our LO is will be 1 tomorrow, and ideally we'd like them to be about 2 years apart, so if finances are okay I know we'll start soonish. How did you guys know you were ready for baby #2?
