Causes
By Mayo Clinic staffSeparation anxiety is a normal stage of development for infants and toddlers. As your child realizes that there's only one of you, he or she may become upset when you're not together — even if you just step into another room for a few minutes. Sometimes separation anxiety is triggered by changes in a child's life, such as a new child care situation, a new sibling or a new home. In other cases, family stress or tension may lead to separation anxiety.
