3-5 year olds go from the anal phase to the curse sensitive phase, they get pleasure from excretion, and at the same time, their language skills are greatly improved. When the two situations come together, the child will naturally be full of ", pee, fart", which is actually a very normal phenomenon, and it is also a sign that the child is developing healthily, so parents don't have to worry too much.
Science education must respect the law of children's growth, and when one day, parents can gladly accept their children to say ", pee, fart", education can be regarded as a big step towards success.
The most important thing is that parents should not always use their own standards to measure their children, or directly label their children as uncivilized, but should tell their children what is right and what is wrong. Because, many of children's behaviors are imitated by adults, not innate.
Therefore, giving children a healthy and civilized language environment is something that each of us needs to pay attention to, and it has little to do with whether you have children or not.
