Every year, Ethan has asked for the "same special Christmas present," his mom wrote on YouTube. "This year we were able to give him it."
He's still not sure what's going on when he reads the front of the card, which says, "To a wonderful brother." But then he sees the printout from his mom's sonogram inside and reads the note.
It reads, "To my big brother Ethan: Have a fantastic Christmas. I can't wait to meet you."
