Hi TheBuffster I am also the mother of a DC with cerebral palsy, right sided hemiplegia. Caused by the birth most likely.
Tbh I mostly blame a series of hospital decisions and one midwife in particular. I also feel guilt though, that I didn’t argue with them more and that I couldn’t push her out quicker. I have learned to push these feelings down however, because at the end of the day these feelings don’t help me or her.
What has also helped enormously is that as DD has grown up the things she is great at have come to the fore and her CP has faded into the background. I am no longer envious of other people’s “perfect” children because my child whilst wobbly (physically and emotionally) is bright, beautiful, interesting, funny and I totally wouldn’t trade her for the “perfect” ones. Right now because a diagnosis is looming, that’s all you can think about and I was just the same - but it will become less and less all consuming until some days you will not even think about it. Also your DC is a baby and physical milestones are so focused on at this age, but that’s less and less the case as they get older and you get to see more of his personality.
One other thing - sleep. DD was a shocking sleeper. I will confess that we got through an absolute ton of calpol and nurofen in the night times when she was an older baby and toddler, as it seemed she would only sleep for more than an hour or two if she’d had painkiller. Her CP was undiagnosed at that time and we blamed teeth, but I now believe that her muscles were hurting her - growth spurts still cause her aches and pains due to tight muscles, and of course as a baby and toddler they are growing so fast. So my advice on sleep would be don’t spare the pain medication - within dosage rules of course. Also overtiredness was and sometimes is still a problem for her so get those naps in however you can.
Best wishes - it will get better. PM me if you’d like.
