Short YouTube advice from Ming @ Agents of Speech describing two core strategies to teach children language: (1) provide abundant language exposure at the childs level (model only the words/phrases the child can use, especially when delayed), and (2) create a need to communicate by teaching and engaging in play so interaction becomes motivating.
There are two key points. Number one, talk enough with your child at their language level, you cannot talk too much because language exposure, it needs to be at the correct level so that you can learn at an optimal rate. Remember that when you're talking to your child and they are already delayed, do not speak in full flesh sentences. If they don't even use words, you should only give them and model what you want them to use. The next step is to create a need. By creating a need. The best way ever is basically to teach them how to play. And when you play, they're having fun. They have a need to communicate with you because with you around, it's much more fun.
