I love that you're going to do this!
We read the bible every night with our girls. It's been part of their bedtime routine since they were babies. They each have their own bible appropriate for their age and we'll read a story or a few verses together before prayers. My teenagers will usually read on their own at this point but every once in a while they'll suprise us and want us to stay to read and pray with them.

I absolutely loooove bedtime and this is a big part of why. I feel really blessed to get to have that time with them.
