The reality star and her husband Michael Brunelli welcomed their adorable baby boy, Lucius Brunelli, in February.
And updating fans on the past two days, Martha called it the “scariest of her life.”
The 34-year-old star posted photos of their adorable tot, and wrote: “Hi everyone, we just had the scariest 48 hours of our lives.
“Looch’s temperature hit 39.8. His whole body was completely limp. I’ve never been so sick with fear. We rushed to the ER.
“He had a huge spew (down my sleeve). Turns out he had a virus. We’re not sure exactly what it was.”
Luckily, Martha’s son made a full recovery, and she continued: “Within a few hours of being seen by the doctor he was back. Feel so lucky to have such amazing care. Our docs and nurses are amazing.”
