Cas-
Thank you for replying to my posts. I see that you are from Austraila. Is that correct? It is interesting to hear the things you have learned about down syndrome. I have never heard of the rapid palate explander?
Chloe doesn't always have her mouth open - mostly when she is tired or concentrating on other tasks. We are working on it in speech therapy and it seems to be improving little by little. We are working on straw drinking, facial massage, nuk brush and frequent reminders - "chin up" or "tongue in".
Hoping it will continue to improve over time. Regardless - she has a smile that will light up anyones day.
