What is hurting?

I was dropping you off at school, and here is the conversation that took place:

Adhrit: "Mama, are you going to work? "
Mama: "I am going to the doctor first, and then going to work."
Adhrit: "What is hurting ? "
Mama: "My stomach hurts."

When I got to pick you up, you came running towards me and said:
Adhrit: "How is your stomach? " "Is it better now? "
Mama: "yes, Adhrit "

You are the sweetest li'l boy I know. You are so caring, and your memory is just out of this world.

I love you very much my li'l bunny.
