When did you know you ready to have a baby?

Meagan
My husband and I have been together for five years now and we feel that we are ready to start trying to get pregnant. We are both high school teachers, so although we don't make a ton of money, we are doing well and have stable jobs. We bought our house last year and live near his family; my family is only two hours away. We have been talking about children for a while, but the past few months we have both just "felt" ready. I'm not one to make emotional decisions, but it just feels right. 
For those of you that had planned pregnancies, how did you know that you were ready for parenthood? Can you ever be truly ready?
