This may be the saddest and most beautiful thing you'll ever see.

Chris Picco's pregnant wife, Ashley, died unexpectedly in her sleep last week. The baby, named Lennon, was delivered by emergency C-section, but passed away on Monday.

Before Lennon died, Chris went into the NICU at the hospital in Loma Linda, California and played the Beatles' 'Blackbird' for him. It quickly went viral on Reddit and is as moving as anything can possibly be.

As Chris wrote:

Dear friends, family, and supporters; it is with an unbelievably heavy heart that I write this. My little fighter, Lennon James Picco went to sleep in his daddy's arms late last night. He was surrounded by family, friends, and the best doctors, nurses and hospital staff in the world. He was dressed in an outfit that Ashley bought for him, with little guitars on it, and wrapped in a blanket made by a dear friend. I am so thankful for the four unforgettable days I got to spend with him. His mommy would have been so beyond joy to see him and to hold him, touch him, bathe him, sing to him - as I have had the privilege of doing. I have been so blessed and honored to love him before he was formed, to cherish him while mommy carried him, meet him face to precious face, and hold his perfect little body while we said "goodbye for now". There are no words, but I wanted to keep you updated, as your love and support has meant more than anything in the world. All you need is love.

A fund has been created to help with medical expenses. Perhaps not surprisingly, the goal has already been met.
