This thread is really upsetting OP.
From what you’ve said it seems clear to me that your husband has dyspraxia or a similar condition which is making these accidents more likely. Like, it’s jumping up and down clear! I don’t have qualifications in the area, but have lived with these ND conditions in my family for decades now so have a lot of informal experience. You do become able to spot the signs and you’ve listed multiple of them here. So that’s my opinion for what it’s worth.
Others seem to believe that your husband is hurting you on purpose, and/or that he shows absolutely no remorse when he hurts you and your baby.
But…I can’t see where you’ve said anything to indicate that? You’ve said repeatedly now that these events are accidents. You haven’t even discussed how remorseful or otherwise he is when you get injured. What you have said is you know he cares, but you’ve implied you don’t think he cares enough because the accidents are ongoing. That they’d have stopped if he wanted them to?
I’m not sure it’s that simple though. Dyspraxia is more than just clumsiness. It can often involve issues with planning and executive function too. Yes, pps with dyspraxia on this thread have described how they work so very hard to avoid injuring their children. But another has said she’s a good mother but can still hurt them accidentally. It’s important to remember that the condition varies in severity from one person to the next.
It’s notable too, I think, that your husband seems oblivious to the possibility that his clumsiness could be severe enough to warrant a diagnosis. This seems to be his normal, perhaps a family normal, as you say his sister is similar. So it could be especially difficult to address without help. He’s likely becoming defensive as well when accusations of ‘not being careful enough’ are made, which is a normal response, though unhelpful.
You don’t seem to like ‘labels’ yourself. Neither did I but I have come to understand that a diagnosis is given for good reason.
It’s certainly not okay that your child and you are getting hurt, no matter what the reason is! You are absolutely right to try to address this. What I’d do is work with him to check out occupational therapists (OTs) or other experts/diagnosticians in your area. Talk to them, tell them what’s going on, get him assessed if possible. See what their advice is and hopefully he can come to a greater understanding of what might be causing this and devise strategies to help. The door hinge stoppers are something to start with in the meantime.
Only if he gets the all clear from OTs etc would I start considering the ‘sociopath’ who likes to hurt women and babies suggestion!
Sorry about the essay OP 🫣
