Training Children To Pray by J.C. Ryle
Parents, if you love your children, do all that lies in your power to train them up to a habit of prayer. Show them how to begin.
Tell them what to say. Encourage them to persevere. Remind them if they become careless and slack about it. Let it not be your fault, at any rate, if they never call on the name of the Lord.
