DD has cerebral palsy, caused by either her premature birth, or by an infection where she stopped breathing 3 days in, or caused by an infection that might have kicked off premature labour. The fact is, we will never know what caused it. And, OP, you will never know.
It won’t help if I or anyone else tells you you are not to blame, you will come to deal with those thoughts and feelings in your own time. It took me a while before it stopped becoming an all encompassing feeling. It took longer for it to become a fleeting thought and that is where I remain 11 years on.
What you are doing right now is grieving for the life you thought you were going to have. That’s an entirely normal process too. You will find your way through it, and find the strength you need to be an advocate for your little boy, but don’t think you have to just get over it, it takes time.
CP is such a blanket term and their tiny brains have so much ability to overcome things, you might find the impact is much less severe than you are imagining. With DD her CP is purely physical, she has poor mobility in her lower limbs. She is in mainstream school, one of the brightest in her class, she spoke early and speaks well. But even if your boy is affected in a different way, there are so many therapies, interventions, teaching methods that can really help kids with CP.
Your life is in turmoil, but can I tell you the best advice we got when we were at your stage? The consultant said, “take her home and enjoy her, what will be will be” I promise you, those first 18 months or so of “normal” we’re really important to me, looking back now I really cherish them. My baby was pretty much the same as any other. I was doing the same mum things my mum friends were doing. It was before therapy and consultations, and equipment, and all the other things that come with a child with CP. Enjoy being mum. Chuck away the development charts, just love that wee boy. You can’t change what is about to happen, you can only take each step at a time.
I’m not sure what is going on with DP, but talk to him, find a way through, if your relationship was solid, you’ll both get through this together.
