We brought Jayden for his MMR jab last Saturday. It was overdue for more than a month - we had so many things going on the past few weekends that I kept postponing it. He had been fine after the jab until yesterday morning, when I detected a slight fever. Since then, he has been listless and lost his appetite. He even vomitted his porridge all out yesterday afternoon. This morning, his fever rose up to 38.2 deg C. Although the doctor had forewarned us of possible post-effect fever, I still can't help being worried. My poor baby. Crossing my fingers that it will be over the soonest.
