Make them disagree with you

The coolest and easiest way in which you could get your child to start writing is to touch on an issue that he or she is really passionate about. If they are, let’s say, big Harry Potter fans, you say something like, “Malfoy should have been a Gryffindor.” They will obviously disagree with you, so here is your chance. As soon as they try to convince you that you are wrong – Malfoy could never be a Gryffindor – ask them to prove that to you. They will probably start enumerating the reasons why you are being inaccurate; this is where you stop them and trick them into writing you a “convince me!” letter. If they are truly passionate about this subject, they will do anything they can to prove you wrong, including writing a letter as evidence that they are right.
