Sam is finally in speech therapy. He has a great therapist that he sees twice a week for 45 minutes a session. Today was his 3rd session. In the past week he has caught on to the bbbbb sound. He can say "bah bye" and wave at the same time, so he know what it means as well.
In addition to vocal, I asked that they show him (and me) the signs for the words, so we have learned the sign for bubbles...I have mastered the sign, I am pretty sure he knows what it means, but is not using the sign yet.
Wish us luck in our learning process.
