We had an appointment with the Pedi today. It went very well. I knew I could have DS1 see a Developmental Pedi without our Pedi recommending it, however, I wanted to give her a chance, because I want to be comfortable with his doctors knowing we are on the same page. After bringing up my concerns she recommended DS1 see a psychiatrist for counseling and a plan for his behavior and anxiety. I mentioned I wanted him to see a developmental Pedi and she agreed that it would be a good idea.
I feel terrible that we didn't start this process earlier but I am thrilled that we are finally getting the ball rolling.
Re: Update - Pedi is onboard
After his first session he asked when he was going back b/c he seems to enjoy it. We even gave him the option of once a week or every other week to give him some control and he chose weekly. It helps that she gives him hot chocolate and talks about his favorite sports with him and has made up games around sports, ha.
