Bedtime: This one's for me

I just said good night to A and J for around the 2,000th time in their lives. We have our routines at night - and I just don't ever want to forget how sweet this is right now, so I'm writing it down for myself.
Every night when I say good night to A she asks me to rub her back and sing a song. Sometimes she picks (longest possible song) and sometimes I pick (why aren't I picking the longest possible song, too? I should be.) She'll pick the Starfish Song or Everything's Possible or I Love You Ali or On the Loose or This Pretty Planet or For Baby. She knows all the words and she'll usually sing along. When she hugs me good night she doesn't let go.
When I say good night to J, he asks me the same question, "Can you tell me about the day tomorrow?" Sometimes I say, it's Monday. And he says, "No, the real way." So then we go through the whole day - from breakfast to bedtime - and talk about all of the things we are going to do. Lately, that's enough for J because he's ready for me to leave him so he can read. Until midnight. Yup. What can I say?
So, I know that it won't be this way forever. I want to remember not to pick the short song.
