Tips and Activities
What You Can Do for Your 30 month old

As your child's first teacher, you can help his or her learning and brain development. Try these simple tips and activities in a safe way. Talk with your child's doctor and teachers if you have questions or for more ideas on how to help your child's development.
- Encourage "free play," where your child can follow her interests, try new things, and use things in new ways.
- Use positive words and give more attention to behaviors you want to see ("wanted behaviors"), than to those you don't want to see. For example, say "I like how you gave Jordan the toy."
- Give your child food choices that are simple and healthy. Let him choose what to eat for a snack or what to wear. Limit choices to two or three.
