Many young children become unhappy when being dropped off at childcare or preschool — even those who enjoy themselves once they settle in. Talk privately with your child’s caregiver to get some ideas on how to make drop-offs easier. You might give your child something special to keep in their pocket during the day, such as a smooth stone with a heart drawn on it.

Perhaps the teacher can ask your child for help with a task as soon as you arrive, so your youngster’s focus shifts to solving a problem: "I’m so glad you’re here! We need your help finding our animal puzzle!"
