My son's bad habit

He has a really bad habit of scratching whichever body part is closest to you. He digs his nails in real deep and it's almost like he enjoys it. Well, tonight as he was lying in the bed with his Papi (his dad), he dug his nails into Papi's chest and Papi reached out and popped his hand. When Hubs told me this, my heart cringed. My child got a spanking!!! But he said my boy tried to do the same thing again but this time kept looking at Jesus to see if he was going to do anything about it. So I think he knows real well what he's doing. Anyway, he's asleep in the big people bed (again) like an angel. We love him.
