How to Use Vocabulary Apps Effectively
Keep Sessions Short
10-15 minutes maximum for toddlers. Their attention spans are limited, and quality beats quantity.
Watch Together
Sit with your child. Repeat the words. Ask questions. Co-viewing dramatically increases learning.
Connect to Real Life
After learning "flamingo" in the app, find a flamingo at the zoo or in a book. Real-world connections make words stick.
Don't Replace Conversation
Apps supplement talking to your child. They don't replace it. The app is a tool, not a babysitter.
Frequently Asked Questions

Most 2-year-olds know between 50-300 words. By age 3, this typically grows to 200-1,000 words. There's a wide range of normal.
