A child accustomed to scribbling with paper and crayons at home, for example, will find it comforting to discover the same crayons and paper in her preschool classroom. Visiting your child's first preschool classroom a few times before school starts can also ease her entrance into unfamiliar territory. While you're in the classroom, let your child explore and observe the class in her own way, choosing whether to interact with other children. The idea is to familiarize the child with the classroom and to let her get comfortable. Although it's necessary for parents to acknowledge the important step their child is taking and support her, too much emphasis on the change may heighten her anxiety.
Toddlers have an ability to pick up on their parents' nonverbal cues.
If you feel guilty or worried about leaving her at school, your child will probably sense that. The more calm and assured you are about your choice to send your child to preschool, the more confident your child will be. For specific medical advice, diagnoses, and treatment, consult your doctor.
