What do you think is the significance of taking a three-year-old child out for a trip?

I think it is very meaningful. Many things don't mean that there is no meaning without memory. The influence of environment and experience on people is usually subtle. 0-3 years old, vision, hearing and feeling are in a rapid development stage, and behavior, habits, upbringing and personality are all formed at this stage. It is very important to take children to travel, see more, contact more and listen more, stimulate the development of auditory memory, and cultivate children's abilities and habits in all aspects. As for not eating well and not sleeping well, that is relative. Parents can still do well with a little attention.
