Mothers writing letters to their sons may want to express their love and support of the child first, and then detail the reasons for the letter. If the son is younger, stick to shorter words so the child has an easier time understanding it, notes Parent & Child magazine.
Teenagers and young adults can handle longer letters, especially if they are told that these letters are meant to be keepsakes for the future. Some mothers may want to impart a few words of wisdom for those going off to college, adds CNN. Feel free to use a numbered list of things that been learned in life. Above all, keep it light and close with positive words of love and thanks.
