I have a co-worker in your situation. She and her dh have been married for.. somewhere over a year now and even before they were married knew they wanted children. And now they're thinking the time is right. Maybe. CW (co-worker) is excited and terrified all at once. She questions her decision every time she makes it ("yes, it's the right time".. "Maybe we'll wait another month".. etc).
I believe there isn't ever a *right* time. I also believe there's no *wrong* time either.
