I do expect her to be fluent in both languages, and for her age, I think she is fluent in both ASL and English right now -- although I suspect we'll see some delays in both when we next test her (she doesn't get another bout of standardized testing in this area until next year, so the measures I can use are a little rough).
I don't think she's aware of what that means or my expectations. She's a high performer in school, and she is around a lot of children (both hearing and deaf). But our emphasis on language development is always organic (no drilling and we don't do AVT)
She's a very high communicator, I think we'd experience frustration from her if she felt she weren't able to communicate fully due to language constraints -- we've encountered that at two points: when she was wearing HAs, just prior to her CI, we felt a language gap and corresponding behavioral issues (frustrated crying) -- she didn't have enough ASL yet to fully communicate (and, being profoundly deaf with no access to spoken voice, she had no English), and again a year later when we went without a CI for almost a month while troubleshooting some issues with it (a bad babyworn coil was frying her processors). Again, she didn't yet have enough mastery of ASL to communicate. Now that she's been in school, immersed in ASL, I think her ASL is advanced enough to serve her well in such situations.
Both her current bi-bi school and her local school district feel that she could effectively be mainstreamed in September -- she'll be 5, she'll be entering kindergarten. We are currently choosing not to do this, because I think her high-level of performance and strong language development (both languages) is to a large part due to the very specific environment she is in. And, I don't think that we could maintain her ASL development if she moved to the local public school -- we need her to have peers, teachers, staff signing to her and around her, we don't have a social immersion in Deaf culture at home (community, church, a network of friends) and the expertise in ASL as way Faire Jour does, my daughter's school is the key to culture and language.
I see your position and simultaneously feel sorry for you and envy you. Sounds like your daughter is destined to have an interesting life, and you are the right Mom for it.
