What should I say to him if he scatters rice grains on the table while eating?

Do you want to prevent him from spilling it on the table, or do you want to prevent it from being wasted.

For the latter, you can choose to pick it up and eat it directly, and your children will follow suit.

The former can tell him a story:

The little brother was eating and playing, and dropped many rice grains.

The big rooster on the side was very happy: "Haha, good luck, good luck, I found a leaky little brother. Now I can eat to my full!" Eat the rice grains scattered on the ground It's over, dunk dunk, the big cock starts to eat the rice grains on the little brother's pants again. Oh, little brother still has a grain of rice on his chin! The big rooster flew up and pecked the little brother who was playing. The little brother cried and called his mother, but the big rooster laughed at him: "You are a leaky mouth, let me eat happily haha!"

The little brother asked his mother: "Mom, is my mouth leaky? ?" His mother told him: "Your mouth is not leaking, because you didn't pay attention to eating, and the rice fell off."

The little brother went to find the big rooster and said to it. : "Big cock, let me tell you, I will never miss a grain of rice again, I will be a good baby!"
