Prudently stretch the goals and the risks of your children. They will reap the benefits in greater self-confidence, and so will you. Children love their mother. Furthermore, they love to see that their dad loves their mom, too. Make sure that your kids see you display affection to your wife.
Children find security and love when they see their parents together in loving harmony.
Just as children feed off the affection that they see in your marriage, they also feel the tension. The problem here is that children have the tendency to blame themselves for your marital discord and tensions. If you're in love, then show it to your kids. If you're experiencing some tension and disharmony in your marriage, then try to resolve the problems with love, honesty, good judgment, and the happiness of your children in mind. Let your children know through example that you are a hard worker at your job, around the house, and in your physical exercise.
