Hi Spur
My ds has PVL and is now 2 years old. His was picked up on an ultrasound scan when he was 5 weeks old. He was born 9 weeks premature and it is not clear whether the damage occured in the womb or at birth.
So pretty much like you, a bombshell hit me and I took him home from hospital after being told to wait and see. Just by looking at the brain injury, there was no way they could tell me what my ds was going to be able to do. They just told me he may have difficulty walking and talking.
In the meantime we have had fantastic input from all the services, physio, OT, SALT and portage etc.
Fast forward 2 years and my ds can sit for a little while unaided but he can't crawl or walk. He has a standing frame and a seating system that enable him to be supported while playing.
He has about 70 to 80 words now and we are working on him putting two words together!
I have fully been expecting a diagnosis of cerebral palsy for the past year but it is still yet to come.
I agree the uncertainty is unbearable but it does get better. It is hard to come to terms with but time really does help.
Early input is vital and it sounds like your dd will be getting all of that. My advice is to say yes to everything that is offered. You can always stop what you find she won't need later on. I found that going to a special needs playgroup and meeting other parents in the same boat as me really helped.
