When someone is having a second child, you can't make jokes abut learning to change diapers. They already have a kid and have taken care of a newborn, so you must approach your message in a different way. You do have an opportunity to write something specifically related to having a second kid. Having another child does change the dynamics of the family. Two children are at least twice the work, because they interact with each other. The older child will have to adjust to someone else getting more attention. And the whole family will have a new little person to look watch over.

You proved that you make cute babies with your first one. Now you're just showing off!
You've had practice with your first child, and I've had practice congratulating you on your first. We're both getting good at what we do!

You're on number two, and I'm wondering just how many you will accrue.

As I asked myself what I am congratulating you for, I realized that you produced another live person from just a couple ingredients. That's kind of a big deal, I guess. Did you use the same recipe that you did last time?
