I'm cradle, too. I still remember when I was baptised, chrismated and given Communion then. I was 5 years old.
As for my family, none of them (except my late paternal grandmother maybe) is/was religious, they identify as Orthodox, but they know almost nothing about Orthodoxy, Christ, etc. My grandmother also didn't know much about Orthodoxy, but she used to go to church regularly, she was trying to keep the fasts and from time to time communed. When I was a child, she took me occasionally with her to the church on Great Friday and Pascha. I was 17-18 years old when actually discovered Orthodoxy and Christianity as a whole.
Sadly, being Orthodox here (Balkans, Eastern Europe) is more an ethno-cultural thing, maybe like Roman Catholicism and Protestantism in Western Europe.
