You have entered a world of wonderful people and exciting challenges, with some heartaches thrown in - that part you're already beginning to experience. My 20 yr old granddaughter is here with me for a couple of days recovering from having her wisdom teeth pulled. She was the same size and gestational age as your daughter. They gave us lots of their ideas about what she would & wouldn't be able to do in life, and almost none of them were accurate. They'll make some educated guesses. The best advice I got from a dad of a severely disabled grown child was "forget the numbers, forget the comparisons". Every kid is unique and precious. They all need unconditional love and someone to advocate for them. We got many services for Alicia at Children's Hospital. The neurologist everyone is grateful to is Michael Nigro, DO. He has several offices and is not a warm/fuzzy guy but will tell you the truth. Dr. Chinarian at Children's was the one who followed Alicia and prescribed braces, PT (theirs is wonderful there) and other stuff she needed. Super-great guy who loves kids! The rehab staff at CHM is fantastic and you'll meet lots of great folks and see some kids worse off than yours, which will help you in a weird way.
Alicia doesn't walk but she's in community college and working part-time, though she has some learning disabilities. She's a spunky, cute gal. She has a boyfriend who's also in a wheelchair and they text & talk a lot.
Please open your heart to the good stuff ahead and don't worry too much about the negatives. The one good thing about CP is that it's not going to get any worse than it is right now or threaten her life, not on its own anyway. It's kind of like having had a stroke. With rehab, improvements can be made but there'll be a ceiling on that which you can't find out yet. Usually kids with CP are very happy and aren't in pain unless they're doing some rehab that stretches things or recovering from a surgery, which she may or may not go through. We have a friend who has mild CP and has 3 kids.
Our Alicia races with a handcycle in long races. She's amazing, as your daughter wil certainly be too.
Good luck!
By the way, this whole experience made my daughter (A's mom) decide to become a doctor, which she now is. That's why I am so involved. This has all changed all our lives for the better.
God is with you and loves your little sweetie and, if you trust in Him, you'll be amazed at all that happens!
