What If Progress Is Slower?

Some children take longer. That does not mean AAC isn't working or that they won't get there.

Factors that affect timeline include the child's age at introduction, the consistency of modeling across environments, the number of communication partners who actively use the system, the child's motor skills and vision, and the fit between the AAC system and the child's needs.

If you're modeling consistently and seeing no progress after 3 to 4 months, talk to a speech-language pathologist with AAC expertise. Our guide on what to do when AAC progress stalls covers common reasons and solutions. The system might need adjustment. The vocabulary might not match your child's interests. The display size or layout might not suit their motor abilities. These are solvable problems.

The Long View

This guide covers Year 1, but AAC is a long-term process. Many AAC users continue expanding their language skills for years. Some eventually transition to primarily spoken communication. Others become lifelong AAC users who communicate fluently with their devices. Both outcomes represent success.

The goal was never to make the device unnecessary. The goal was always to make communication possible.
