I’d intervene quite honestly and take over the parenting. Nothing is more important than security and wellbeing whilst growing up. You’ve tried talking, suggesting, it hasn’t worked. You need to up the ante and intervene. There is emotional damage here, it’s not just in the zone of ‘good enough parenting’.
Your DD getting this upset every day is not on and it HAS to stop.
I have a child with disabilities and my Ex was trying, in his way, but our child was getting really angry every day, and upset. Ex was only doing bedtime, and wasn’t getting angry or anything but still, our child needed a certain way and he just wasn’t getting it. Ex was quite hostile to any suggestion, no matter how respectful and diplomatic I was.
I had to say to myself, is my child being distraught every single bedtime OK? And no, it wasn’t. So I intervened, I finally said look this has to stop, our child cannot be this distraught every single day. We can get a professional to advise, he can pass it over to me, we can try my suggestions. I didn’t care how, but it HAD to stop. I got called all sorts of names by Ex, got told I was controlling, that I wanted to do everything. (Believe me, I was utterly exhausted and desperate for time off). Ex was awful to me for weeks and I was ready to leave the marriage. Awful. But Ex, although we did break up eventually, did learn how to parent our child in a way that frankly didn’t leave him with lasting damage. So now I also trust him a lot more, and he did, eventually, realise that our child did not have to be so upset, and that it was us as adults that were the cause, not the child. Hard lesson, but needed to be learnt before real behavioural and psychological harm set in.
And crucially our child now does not get distraught every single day and we both parent feeling much happier ourselves.
