As I have said before, simply increasing your child’s emotion vocabulary improves their emotional intelligence. It makes sense that in the process of exploring new words for new feelings we tune in to those emotions and they are added to our repertoire of awareness. Next time we feel the emotion we have just learnt a new word for, we can express it readily too of course.
Generally, our emotions are not focussed on other than when the reactions to them are extreme. We are not in the habit of tuning into our emotions in a healthy way. One, really simple but effective way of helping your child (and you) become more emotionally literate is to do an emotion check-in every now and then.
