Tummy Bug?

So, was it the stomach flu? I guess we’ll be finding out in the next couple days. My oldest son, randomly threw up yesterday at 3pm, and then at 6pm. After each episode he was happy and running around again. He was also hungry and wanting to eat. I don’t think he had a fever, and didn’t appear to have the chills, or aches. So, what was it? I pray that something didn’t sit well with him, and that it wasn’t the flu. But, I guess we’ll be finding out if it was contagious or not in the next couple of days. I loathe the stomach flu. Did I mention I don’t like it? If we get it, then that is God’s plan for us but I hope it’s not.
