She captioned the post:

"Long story short- we took our little dude to the pediatrician yesterday for a bad cough he developed and ended up in the pediatric ICU. We’re still here and probably will be for a couple more days. Isaiah’s got bronchiolitis and his little body is having a tough time getting enough oxygen."

Catherine commended the hospital staff for how they handled their role:

"He’s not having the best time but the doctors and nurses have been great and we’re just super thankful we took him to the doctor when we did. We’re confident he’ll be just fine but prayers are always welcome."

Bronchiolitis typically infects toddlers and infants. It is usually not fatal, however. The illness leads to bronchioles or inflammation of the lungs and breathing difficulties for patients.

Sean also shared the same post and caption. On Saturday, Catherine gave a positive update about Isaiah. Throughout the ordeal, supporters sent lots of prayers their way.

"Holding my little one so so tight. Thank you for all your prayers and sweet comments. I think they’re working."

Isaiah was born in May while his two-year-old brother Samuel Thomas was welcomed back in 2016.

Sean was actually the third-place finalist on "The Bachelorette" in 2012 before starring in "The Bachelor" a year later in 2013.

The 34-year-old reality star put another post on Sunday night saying that Isaiah was "making good progress" and "in good spirits. A smiling photo of the baby boy accompanied the text. He was finally released from the hospital just 20 hours ago.

Back in early October 2018, a former "The Bachelor" contestant sadly passed away due to a seizure.

On October 3. Cristy Caserta, 38, fell from her desk while attending class in Sunrise, Florida. She was going through a seizure.

Emergency responders administered CPR before transporting her to Westside Regional Medical.

Unfortunately, Caserta passed away. She had been a contestant on season 15 of the show in 2011 but was unsuccessful.
