The app was designed for 2-8 years old. However, parents and therapists use our app with great results with kids as young as 16 months. But please be very careful with screen-time dosage. Just 10 to 15 minutes a day of speech-blubbing is more than enough for a 3-year-old. If your child is younger than 2 years, use it 5 to 10 min a day max.
We invite you to read our blog post about screen time, where you will find professional guidelines and also suggestions on how to implement quality screen time!
