Luckily, he is okay!
They were forced to call emergency services to their Hidden Hills home around 10pm. The medics spent a few minutes inside before taking Mason, who was fully conscious, on a gurney to the hospital.
"Scott was terrified," said a witness. "He was clearly pretty worried about whatever was going on, but Kourtney was far more in control of the situation."
Kourtney walked out of the house clutching Mason, until paramedics convinced her to sit in the ambulance, but that baby was not fazed by the commotion. She rode in the ambulance while Scott followed in his Mercedes sports car.
It is not known why the paramedics were called.
Hopefully, it was just a safety precaution and everyone is doing just fine!
Update: Apparently, little Mason suffered an allergic reaction to peanut butter!
