Horseshoe, I'm sorry to hear of your situation. I don't know if this will help, but I'll say it anyway.
Our dd was born profoundly deaf. No idea what the cause was, there's no deafness in my or dh's family, and our 4 year old ds is fine. Dd failed newborn hearing tests and we were subsequently told she had moderate hearing loss: we were sure this was worse, and our fears were confirmed when she was about 9 months old.
You will doubtless go through the 'why her/us/me?' scenario: well-meaning people - with 'normal' children - will tell you it could be worse - and you'll want to deck them because, as far as you're concerned, this is as bad as it could get for you, because it isn't what you expected or planned for. You'll feel envious of people whose children have four fully functioning limbs, and will rage inwardly (and outwardly) if your child cannot do the things other children can. I've been through - and am still going through this - with dd, although starting to come to terms with it now. It's a process I feel I have had to go through, but it's ultimately draining and it doesn't change anything. I do have days when I feel very down about the challenges dd faces, but it's better for me personally to concentrate on the positive.
I have to remind myself to focus on this: dd is a normal little girl - she just can't hear anything. She'll still want to do all the things that little girls want to do - just as your dd will - wear pink, play with Barbies, have sleepovers, wrap parents round her little finger etc. It's up to me and dh and our family to emphasise the normality while ensuring she gets the support and assistance she needs. Her deafness is a big problem - there's no doubt about this - but I don't want it to define her as she grows up. I also don't want her to use it as an excuse for being treated differently.
It's actually dd's first birthday today, and the past year has been an odd combination of the best of times and the worst of times. Looking back on a year ago, I never thought I'd be where I am now, with a child facing major surgery in the next 6 months in the hope this will enable her to hear some sounds (she's being assessed at the moment for cochlear implant). Equally, I never thought I'd have such a wonderful, happy, contented, beautiful daughter - and for that I am extremely grateful.
Thinking of you
