I think the most valuable thing is the child's world. The world they see is different from what adults see. the sky is overcast. It is just pure black in children's eyes，but the adult will see the coming rain. When I think of food I really enjoyed as a child, it's chips and sticky toffee pudding. Even if there are a lot of unhappy things, I will be happy immediately while giving me these food. It is said that children think and speak with an ignorance of convention. so，if they said impolite words，please forgive them and tell them not to do this next time. Children's wit is to attract parents' attention and they wants get more love，so don't break the goodness in their heart.
