My 2.4 yrs old son is assessed with mild delay in speech by a speech therapist. Besides going to speech therapy which is 1 to 1, any class that is in a small group where he learns to interact? What other things can we do at home to help him?
your speech therapist should have some exercises for you to practice at home; if not, ask him/her.
one of the 'exercises' that my ST got us to do is to ask questions about a book; ie, we don't have to read the storybook word by word, but we look at the picture and try to engage in a discussion with the child. if the child's sentences are not complete/proper, we will have to say it in the proper structure and get the child to repeat our sentence. key note is to only do it about 15min or half hour daily (depends on the child's attention span) and don't over do it as some speech-delayed kid may find it frustrating as they cannot grasp the sentence properly.
another thing is to switch off the TV.
