Bode Miller's son suffered a seizure on Monday and was rushed to the hospital ... but, thankfully, the little boy is now home and resting comfortably.
The Olympic skier's wife, Morgan, detailed the horrifying experience in a social media post on Tuesday ... saying it painfully reminded her of when the couple's 19-month-old daughter, Emeline, tragically died following a pool accident in 2018.
"Life is constantly walking a knife edge and it's not something we are unfamiliar with," Morgan wrote alongside a photo of Bode and 3-year-old Asher in a hospital bed.
