This issue is common with young kids, and it's understandable. They prefer doing things right away instead of just waiting. I once read that little kids can't really think about the future. So, when parents say they have to wait until tomorrow, the kids get upset because to them, tomorrow seems really far away. I think this inability to understand time might be why waiting is hard for them, which makes sense.
这个问题在小孩子中很常见,而且可以理解。他们更喜欢马上做事,而不是等待。我曾经读到,小孩子实际上无法想象未来。所以,当父母说他们必须等到明天时,孩子们会感到不安,因为对他们来说,明天似乎很遥远。我认为这种无法理解时间的能力可能是他们难以等待的原因,这是有道理的。
