he got hurt

My husband is in the backyard grilling chicken and my kids are there too. They are playing baseball while their daddy is cooking. My son just came in crying. He said he got hurt and when I checked he had bruises on his knee and arm. He was screaming for a bandage. I asked him to take a bath then I would put a bandage on it. I asked his sisters to get in the house. I am worried that they might get hurt too.
