Preparing for a Child's Birth

i have young adult people to whom i gave birth many years ago. And that's one of the things that i'm constantly trying to help them understand, which also makes me kind of naggy sometimes. But it's like, i can't tell you what's going to happen, but i know some thing's going to be unexpected. That's part of it. I feel like the older i get, the more mature i get,. hopefully, i just know that that's going to go away.
