"It was scary and it broke my heart seeing him like this, but we are so thankful to be back home and on the mend🤍," she adds, also including a photo of her baby boy after he returned home.

According to the CDC, RSV is very common in infants and kids, with an estimated 58,000 children under 5 years old hospitalized each year in the United States due to the virus.

On Thursday, Patterson Caldwell shared an update on her Instagram Story, posting a picture of her other two children, daughter Emmaline Rae, 2, and son Graham, 3, cuddling next to baby Pearson at home.

"Gangs all here 👦🏼👧🏼👶🏻 These two are very happy to be reunited with their little chunk🥰," she writes.
