Anytime a new baby is introduced to the family the parents always worry about how the older children will adjust to having a new addition to the family. For one lucky mom and dad, the transition went much better than they had hoped.

This little boy immediately falls in love with his tiny baby sister the minute his mom and dad place her in his lap. It wasn’t long before he broke into song and was serenading her in song.

The little boy chose the song, “You Are So Beautiful” by co-writers Billy Preston and Bruce Fisher. The song was originally created to honor Preston’s mom.

When Preston found out that other musicians were using the song meant to serenade his mother to attract women, he was furious. So upset that he would call them and chew them out.

We’re pretty sure though that he would approve of this little guys rendition and choice of words for his new little sister. The little tot looks into his sister’s big eyes and tells her how beautiful she is with some of the most heartfelt lyrics ever written.

I can’t even imagine what his mom and dad did when they realized what this little boy was doing as he gently rocked the tiny baby back and forth in his arms. Everyone in the room will remember that moment for the rest of their lives.

Check out the adorable video below and be sure to share it with your family and friends. It will absolutely melt their hearts.
