This product is generally for kids ages 3-5 years. Some of the activities, and the books and songs could go as young as 2 years.
Here's what I recommend. Before you start any of the activities, watch the incredible BONUS What Your Preschool Schedule Should Look Like by Age.
In that video a veteran preschool teacher will walk you through exactly what types of activities your child should be working on at ages, 2, 3, 4, and 5. The ideas and tips she shares in there are GOLD and you can use them not only during Mommy and Me preschool time, but also for the rest of the day.
