You can help your child process emotions of any kind when you see him facing some hard time.

Following is a simple practice to do so:

Usually when the children become angry, sad, or severely upset, we try to distract or redirect them away from the painful feelings. But this isn’t always the right hing to do. Research suggests that the best strategy is to spend time with children supporting them deal with the negative emotions they experience. 

Practice these 3 steps to help strengthen your bond with your kids:

1. Raise awareness: show that you are curious about their experience rather than impose feelings on them. For instance, say, “I’m wondering if you’re sad?” rather than declaring, “You’re sad.” This approach shows your children that you acknowledge that their experience is personal and that you are able to understand. 
2. Name the feeling: Encourage the child to talk about what they feel, then take a few moments to reflect and give a name to the emotion. You can say, “It sounds like you’re feeling angry,” or “It sounds like you’re sad.” This way you help them cultivate a bigger emotion vocabulary and show them that expression is one way to regulate difficult emotions. 
3. Explore together: Validate the children’s emotional experience. This can be as simple as saying, “That sounds like it would be disappointing.” Help them make sense of the experience that is confusing to them, such as mixed emotions. For example, kids can feel happy a friend won an award but, at the same time, sad because they also wanted the award. match their emotions with your voice, face, and touch. You may share a smile if the child is excited or hold his hand if he is nervous. These non-verbal communications can help children recognize and make sense of their own feelings.
