Ladies and Gentleman...we have the /F/ Sound!!!!
We've been waiting. We've been working. And yesterday, out of the blue, we had this exchange:
Christian: Mommy, cut my cheese stick please?
Mommy: Buddy, you can just bit it, it's ok.
Christian: Mommy, you use a kniFe to cut it. Please!
Mommy: Seriously, Christian you don't need....OH MY GOSH! OH MY GOSH! SAY IT AGAIN! SAY KNIFE! YOU DID IT! SAY IT AGAIN!
His initial /f/ is still a bit weak...but we're getting there!
GO CHRISTIAN GO!
