Personally speaking, I think parents should allow their children to make mistakes, because children can gain experience from mistakes. For example, if children mistakenly spell English words, after realizing that, they will obtain a clear impression on the right spelling. Also when studying mathematics, if kids’calculation did not reach the right result, they will try to find their mistakes, correcting them, after that next time when they do the similar calculation, they may not commit the same mistake. In a word, sometimes mistakes are the good teachers, helping children to grow.
