After regaining composure, your child should be able to have some insight about his or her inappropriate behavior. Sometime your child should be able to laugh about how ridiculously he or she had behaved. During this period of adjustment, your child should continue to show a need for emotional closeness and support from the family. Preteens and some teenagers may not want physical closeness, like a hug. You should not interpret this as a rejection or their not wanting to be close.
Some children get uncomfortable with close physical contact.
Your past experience with your child will tell you better how to interpret the repulsion. Your child still needs and should still respond to praise and encouragement. After a time, your child may need help if you can't get a smile. This list is not all-inclusive, but it should give you some idea about what to look for. Again, if you are worried, get professional help from a therapist that has experience with children and teens.
