Saab Magalona's heart melted when she caught her son Pancho softly giggling in his sleep.
Teary-eyed, the celebrity mom shared the heart-thugging moment in her post.
She wrote, "Some say that when babies are laughing in their sleep, it means they are playing with angels.
"So I asked him if he's playing with his guardian angel, his twin sister Luna. Watch the video to see how he responded [heart emoji] [loudly crying emoji]"
In the video, when Saab softly asked Pancho if he was playing with his late twin sister, the little boy smiled in response.
Luna passed away on February 8.
During the recent long weekend, Saab honored the memory of her late daughter by visiting the twins' unfinished nursery room.
She began cleaning up the room, "filling up boxes with clothes, toys, and supplies with donations."
Still, there were some items that Saab could not let go.
She wrote, "I still cannot let go of her car seat, crib, and the twin stroller. It’s going to be a long process."
The post ended with hashtag "#ihadastillbirth" and tagged the Instagram account @ihadamiscarriage.
