The pitter patter of little feet doesn't last too long, does it?
My kids were all very VOCAL children. Started when they were little babies screaming at a pitch that would take the paint off the walls.....I don't know how I still have my hearing. As the kids got older they started mixing their screaming with whining, so it wasn't as loud. It didn't really change until the older ones got into their teens when their screaming and whining turned into a much quieter form of communication.....manipulation. This subtle form of manipulation by smart teenagers is something that never goes out of style. I did it with my parents, my kids did it with me, and if there is a God, their children will do it to them.
I suggest putting a room aside, padding the walls, and let the kids scream as loud as they want. Your sanity is worth it.
