Breaking my heart

So Owen started running a fever after we left the doctor's office yesterday. He was acting fine at the office and by the time we got home, he was sleepy and feverish. We hung out at home and watched tv, cuddled, and napped on the couch most of the day. He woke up from his nap crying, "Mommy, Owen's belly hurts!" It was breaking my heart hearing him cry. He's never really been sick before, so this is all new to us. So sad.
