the superhero with the achy tummy

Dennis was just not himself today. He slept very late and was whiny and clingy at church (weird for him). He cried when I picked him up, refused to speak to anyone, and complained of a tummy ache. He ate when we got home and said the ache was "just a tiny bit" after that. He also convinced me to get him the Captain America mask and shield that had been marked clearance at Walmart (the last of each item in stock). He tried them on and played a little, but then he asked for Sprite to help his little tiny tummy ache. I wonder what's going on with him. I hope it's nothing major. I just hate it when he doesn't feel well.
