Hi J.!
I have one of those girls! My DD is deaf, Blind in left eye-legally blind in right, developmentally delayed (she is 4yrs old in some areas and older in others) mild CP, and few other issues. When she was little she was patched for cross eye (till found out allergic to patches)had first cateract surgeries at 9 and 10 months. her nystagmus cleared up when she gain more vision fortunatly, and about age 5 had surgery for cross eye.
First off remember Dr's are great but usually not sure about anything and will give you worse case senarios usually. With my daughter at first i was told she would probly not survive, then she would be a vegtable. So i rarely take Docs word for gospel. LOL! We went through it all being told no, she won't sit up, she won't walk , etc. I hated Dr's and being told no! But the good news is my Daughter is now 30 years old andlives independently with part time staff and family support. She will never live totally independent but does really well in her situation. I had an Aunt who helped raise me and taught me not to raise her handicapped and i took her advise to heart, and see this as the reason she has done as well as she has.
Follow your Gut! If it don't feel right to you don't go that direction. Expect her to do things encourage her to do all she can, gently push her at all times. You will be rewarded in the end, even though the end is a long time off.
We have been very lucky She has been healthy, had many small health issues, as well as ones that seem large at the time and later aren't. She didn't walk till she was over 3, and didn't ever crawl! She was a roller. She has been put on meds last several years now because she has some behavioral and psycologiacal issues, but that all tends to come from her being a Ruebella baby and other issues that caused her problems. I just want to tell to hang in there and keep going she will thrive and bring lots of love and joy to your family! Hugs and support all around you! P.
