It is not unusual for a young child to have separation anxiety from a parent. At times this occurs just as the child begins school, and at times it comes at a slightly later date. Generally the best thing to do is to reassure them that you will see them again later that day, and then leave; try not to linger longer, because it will teach your child how to get you to stay and not leave. You can also give your child a token or two, such as couple carefully chosen (laminated) family pictures that he or she can look at throughout the day to “feel closer” to you. “Happy memory” pictures work well for this. If the behavior continues or worsens, you may need to probe further into what may be causing the fear. Talking to the teacher about your child’s behavior during the day may help shed light on the situation. If all else fails, it may be advisable to bring your child to a professional.
