Every time she hears the news, this adorable grandma with Alzheimer's is beyond happy to learn her daughter is having a baby.

Remember how overjoyed your parents were when you told them you were pregnant for the first time? It's a moment you will always cherish, but cannot relive. Unless you are mom-to-be Christine Stone, whose mother Setsuko Harmon has Alzheimer's disease.

Since she can't remember things day-to-day, Stone has told her mom the exciting news that she is expecting over and over again. And Harmon's reaction is just as sweet every single time.

Stone recorded herself giving her mom the happy surprise that she is going to be a grandmother on multiple occasions, and posted the resulting video mash-up to YouTube.

According to The Huffington Post, sometimes Stone will tell her mom she is pregnant more than once during a single visit.

Watching Harmon's repeated joy about the pregnancy is both sweet and heartbreaking. It's wonderful to see how happy she is every time Stone tells her the news. But also, I'm imagining how difficult it must be for the mom-to-be that her mother doesn't remember she is having a baby from one moment to the next.

"I wanted to have a video for my daughter to see how excited my mom was for her arrival and how she was loved by her." Stone told HuffPost. "I also thought it was adorable how my mom reacted every time." Stone also hopes to raise awareness about Alzheimer's and added another important takeaway from her video: "I also hope people take time out of their schedule to spend time with their parents, because they won't be around forever."

Noted, Christine. Thank you for this important reminder, and for sharing your very personal story.
