@Ngaiz: thanks. It looks like I am out of luck if paed isn't willing to write the right script. I did pick up the script today. He wrote s26 lactose free. When I asked, the receptionist said aptamil isn't on the schedule. I am not sure if paed made the mistake and didn't have time to make another phone call. The paed is doing it as a good will, I guess. So no go with a GP? DS stomach is so sensitive. Any chance of formula will upset him. He and us have gone through enough. I am not keen to switch formula again.
I drove 30 mins for the script. Well, I spent $$ for a 5 mins consult last week, and many appts (4 specialists) to sort out DS issue. I was hoping this would save me some money. Sigh...also losing my job in a few months.
