Improv prayer by a 3 year old

Yesterday as a special treat Isaac got to buy a pack of gum. His favorite gum flavor is mint. He tried spearmint for the first time and liked it. Well we got back in the car and as we were driving off he said, "Oh God!" I paused not sure whether to scold him for using God's name in vain or ask him if everything was okay. The thought was interrupted by him continuing, in a voice he uses in prayer. "Thank you God for this gum. It is yummy!" I told him what a good job he did and that God was probably very proud of him too.
