Now how do we turn it off?

Our daughter turned three still not talking. This concerned us, so we took her to a developmental pediatrician. He told us she had PDD and she started speech therapy immediately. We also began iron and omega 3 supplements. Her vocabulary bloomed!...at home. She wouldn't speak in her therapy sessions. We had a happy girl, adding 3-5 new words to her repertoire DAILY, but had to go back to the Dr. to discuss selective mutism.

Turned out the problem was me. I had always sat through her sessions, but one day I dropped her off and left the building. I nearly cried - she is my baby after all. The therapist, on the other hand, was delighted. Caroline talked! To everyone! That child came home loaded with so many stickers her shirt dragged down in the front!

Now we can't get her to stop talking. Or singing. Or humming. We always know where she is, at least. We worried, we primed the pump, now how do we turn it off?
