I have worked with infant, toddlers, and preschoolers. I was infant head teacher. I would introduce the parents into the classrroom and talk about what we do in the classroom and what kind of activities we do. I write daily report about their day and we write when and what they ate, when they nap, and when they were diapers change. We do a lot of belly time so they can lift their head up on their own and learn how to roll over. We take them out for a walk.
