Thank you all, I'm just having the Momma "what if" guilt and trying not to let the cart get before the horse. We have appointments for next week with a specialist.
We're hoping it is just fluid build-up that can be drained. Then there is the whole "gray area" of hearing aids, ocular implants, tubes, etc. Worst case scenario is, we have no options except speech and visual language therapies, but that is really unlikely, and not "the worst thing" as we've been teaching her sign since she was tiny.
We have a great community with lots of resources available, so I'm trying to stay positive no matter what happens.
Thank you again, this place and all of you, really do help.
