Whether it’s your five year old starting Kindergarten or your 18 year old shipping off to college homesickness is a normal, adaptive process. Being homesick is really just a deep need for love, protection and security. The cure is allowing your child the psychological space to go through these experiences. Rescuing them or hovering is more about alleviating our own parental anxieties. We should love our children enough to let them experience this so they mature and grow up which produces healthy, psychological independence. CNN has a great article about homesickness.
