Video tape your child the first week, and then at three month intervals. Most parents will see progress after that first tape . It's more concrete, it's not like when you take your child to therapy and observe, and the therapist says teach your child to respond. Much more specific road maps guide you and the video clips let you see it over and over again. You learn how to help your child without overdoing.
Parents do everything for their child.
If I go to the gym and the weight is too heavy, I lift it for the child. Learning different forms of teaching is critical to make your child available to learn. Not just what you say but how you say it. By not having only a singular approach to teaching a learning concept of big and little, you are allowing child to have a specific set of demands, which is organizing for your child. They learn those words as with those demands and learn how to react not so confused.
