I don't have kids yet, but I remember what my parents did for me, for the most part:
On most nights, we would read three books together. I started learning at 2 1/2...which is also where my memories started. Reading was about the only thing that could make this wild ADHD kid calm down for bed!
I'd quit taking naps very young, so bedtime was earlier for me than most kids.
Then my parents would turn out the lights, we'd say a prayer together, and then they'd sing me lullabies.
Like I said, I was a hyper little kid, so for a little while with the lights out, I'd play with my stuffed animals and act out little stories. My parents knew I just needed to burn off the energy before I could sleep, so they didn't say anything unless I got loud or turned the light back on.
On some nights, as a special treat, I did get to watch certain kinds of movies before bed--I had two Disney lullaby tapes that I still remember very well. In the house we had when I was very little, we had this furry rug my dad brought back from a trip, and there was actually a fireplace up in the master bedroom, and this rug sat in front of it. I have great memories of winter nights when my parents would light the fireplace up there and I'd lie down on the rug and watch one of those videos before going to bed.
They never played stuff that was going to get me hyper again, though!
Good memories.
