Hope, I'm so glad that you're experiencing a bit of peace.
Regarding the childcare handoffs, I think you need to be clear on your motivations. I have been bugged by similar things with my STBXH, and have insisted on basic courtesy because I feel that it's important for our children to witness basic polite interactions between us. In your case, though, you need to do a cost-benefit analysis. If asking for that is going to create more conflict, then it's not worth it IMO, either for you or your S. Hopefully things will normalize eventually.
