It's always something

Tonight Colton was sitting beside me,  feeling his heartbeat.  He freaks a little and says "mom,  my heart is beating crazy; skipping and stuff". So I put my hand on his chest and count beats for several minutes,  no problem.   I go back to crocheting and a few minutes later he grabs his stomach and says he doesn't feel good.  The very next second he JUMPS up off the couch, screams and yells while crying "I don't have a heartbeat! !"
HUH?? Jess and I try not to laugh because he is seriously distressed.  I then explain things to him. I'm not sure what he is all worked up about but I think maybe he needs a few calming prayers tonight.
