These people might be the happiest family in the world. Words can't express the perfect, peaceful happiness I experienced in their home. It was even more magical to see them with their miracle baby boy than I expected. And seeing them both transform into different, even better (if that's possible) people than I knew before really brought tears to my eyes. I think I actually went home and snuggled and kissed and hugged my own kids more because the wonder in their eyes as they looked at their son reminded me how incredibly blessed I am.
Writing congratulations doesn't feel like enough, but a good place to start. Love you.
