How can I prepare my child for preschool?
Visit the nursery or playgroup
Make sure you and your child visit together. It's a good time to sell the joys of preschool, showing your about-to-be-preschooler activities you know they'll be interested in and talking about the other children to play with.
But never oversell change to children. Tell them that while you hope they'll have so much fun they'll never feel sad, if some rotten kid steals their comfort toy they should tell a grown-up.
