Our daughter's head teacher gave birth to a baby. Should we send a message to congratulate her?

It should be that the class teacher sends a message to congratulate the baby, which is a basic worldly wisdom:

1, children are your hope, and babies are your sustenance. When you are happy to have your son, I want to send my most sincere wishes. May your children thrive, be healthy and happy!

2. Life is three big things, dear teacher. Let me sincerely wish you and your family health and happiness on this day when you are happy to have your son.
