From the perspective of the Book of Changes, is it a good or bad thing for a child to talk and walk late?

From the perspective of the Book of Changes, that is, from a philosophical perspective, we judge whether speaking and walking late is good or bad. If the child does not have any physical disease, there is no good or bad thing in talking and walking earlier or later. We can only tell how quickly a child has developed so far, but everything is in a state of change. Those who developed early may develop slower in the future, and those who developed late may develop faster in the future!
