Dear son-in-law, happy birthday! Today it is with special joy that I congratulate you, because soon you will also be a father. Congratulations and thank you for the grandson or granddaughter you will give me!
I am sure you will be a wonderful father, as you have been an example of a husband to my daughter. Know that I am very proud of you, and I am very pleased that you are part of our family.
Best wishes! I love you, my dear, and it is a joy to know that you will be the father of my little grandson.
