Judaism doesn't shun questions, rather it promotes them. We do everything possible to stimulate the child's mind and get him to question. We are not satisfied to have the child sit back and relax while we feed him the necessary information. We want him to ask for it. A renowned thinker once said that he owes his great genius to his mother.
Questions breed greater thought.
A child that doesn't ask questions may sometimes show apathy. It may show that he's not interested or concerned. It may mean that he couldn't care less. If someone is concerned and really wants to know then he will ask questions. Questions stimulate the mind toward greater knowledge.
