That is beautiful! I can relate to the sentiments...that is how we felt too. I don't think I knew those songs back then.
Jenni, our oldest was on TV...via an ultrasound done right before she was born. They played a special song during "our" portion of the show. (It didn't air until we were in the hospital after she was born.) Her song will forever be....
"Let the words of my mouth and the meditations of my heart be acceptable unto you, OH LORD! My strength and my redeemer!"
