When Heather Clark's 7-month-old son Lukas died in 2013, she donated his organs to three children, including Jordan Drake. Clark was recently allowed to listen to the beating of her son's heart, which is in Jordan, now 4.
Jordan also gave Clark a gift. It's a teddy bear with a recording of the heartbeat that plays when it is hugged. Here is a 14-minute video of the day. The most dramatic moments happen around the 4-minute mark.
