I just really believe if we are going to put her through speech therapy in hopes of her understanding spoken language that we owe it to her to meet her half way by learning and using ASL daily along with speech. If it turns out she has a preference than we will make sure to lean that way be it sign or spoken because the most important thing is that she has language and is being educated properly. I feel the same as you, like those children who are not exposed to ASL and have difficulty learning out to be oral will eventually find signing and it will be life changing for them.
As for St Louis, I was honestly surprised that NO ONE at St Louis Children's Hospital tried to discourage me from pursuing a total communications route for Zoe, they simply asked and then said okay! It is only my EI coordinator who is really pushing just oral only or rolling her eyes when I mention looking for ASL material. But she is so young and we live in a VERY rural area with very few HoH let alone Deaf children so I think she's just ignorant and only knows the CI 'hype' and not the reality of it, like it's a cure instead of a tool.
My other irritation at the moment are my husband's parents. When we first told them of Zoe's hearing loss they said there was no way. When we told them she was deaf they said they doubt it. When we asked them to learn a few basic signs they said she wouldn't need it. When I mentioned something about fluid and her mastoid that the dr thought was a misread of her MRI they said oh well she just has an ear infection. Now they think the CI is going to enable her to be a hearie and are still putting no effort into learning any signs - which is a probably because they sometimes babysit for us. All they know is eat and more, just last night MIL was wagging her finger at her for no, I'm like "Why don't you just sign no? She understands that better." And MIL couldn't remember it even though we show her every time we see her. I know she is older, but everyone else - old and young - are putting in at least some effort. I hate thinking she's going to grow up feeling alienated by them.
