Just to share my personal story with you, since it sounds like you are willing and somewhat cooperative with dad.
In my case, dad lives in texas, I live in Ohio with 18 month old. I usually snap a pic with my blackberry every day, and email to dad with a short "how kiddo is doing." I also have a pic in kiddo's room of dad and dad's other kiddo (my kiddo's half-sis) along with some deer antlers dad sent for kiddo.
Me and dad worked out visitation on our own. Dad can come up WHENEVER he wants, and visit kiddo. He stays at my parents house and plays with kiddo and gets to know him and kiddo is in a familiar environment. At some point I am aware that dad will want to take kiddo to Texas. And we will work it out when it happens. And I know it will, so I'm already ready for it.
I started reading here before kiddo was ever born. I have seen so much "what not to do," that I feel like the relationship between me, dad, and kiddo is GREAT. I know what mistakes not to make. I feel like there aren't any surprises.
And dad sends child support every two weeks. I put it in a special account, where it sits. I am currently building a deck on my house, where kiddo can play in his sandbox. But if that money never comes again, I can still pay for everything on my own. I never plan on it, it is just nice when I can do nice, extra things.
Best of luck to you, dad, and your kiddo.
