This app teaches your child how verbs and nouns combine, how adjectives and nouns combine, and more. It's the critical connection your child needs to advance in language. Right now, your child may have nouns, core words ("more", "help", "all done"), sentence frames ("I want ..."), and even some gestalts. That's good but not enough. In the short term, it makes sense to emphasize functional communication. But in the long term, growth is only possible if your child learns how joining words leads to endless possibilities. This app gives your child the key to unlock their future language development, using a Visual AAC plus step-by-step guided levels. We encourage you to try it with your child.
