Oh what a beautiful name, I've been waiting for you to take this step, I really wanted to ask you when you were going to introduce us to your treasure and look you did it much sooner than I expected.

I wish you good health, may your daughter bring you only joy, and I wish your wife a smooth recovery.

I can't tell you from my own experience yet, but I think this is the best time to start, now it's time for the three of you to learn what the threesome life is like, because you already know the couple life very well.
I'm very happy for you three.
