Most of these are things a HCP did do:
During my last labour, my reheatable heating pad broke and my midwife made some sort of makeshift one and held in on my lower back for me -- not entirely sure how she made it, but it was great. Also talking through my birth plan and not dismissing my fears, but not making a big deal about them either (my birth plan for that one was basically I'm scared, I'm disabled, here's what helps me).
In the time before that, I had a HCA on the high dependency post-natal ward who was very kind about holding my fussy DD while I showered as I was really struggling. Another heath care professional helped move the tub bassinet closer to me and helped me pick her up as I had so many tubes in my arm that it was hard to move. It would have been nice if I'd had more help with water/food on that one.
In that one, I'd had to have a manual placental removal which is why I was on the high dependency ward, and the nicest person - not sure if she was a HCA or nurse - just held my hand and talked to me on the way to the OR and explained why my leg was wouldn't stop shaking and what was going on with my body and the procedure ahead. I don't even remember the explanation now, but I was so grateful having someone talk to me like a person and explaining what was going on and asking about my baby. In that one, the midwife fucked up she yanked on the cord repeatedly, my placenta tore, she then blamed it on me and my 'low iron' and I'd spent the last however long basically be talked over and about without my input -- that bit of niceness made me cry and still brings tears to my eyes.
I found it really helpful in my second labour just having someone talking with me after I gave birth. They helped me get cleaned up and then talked to me while filling in paperwork.
In my first labour, I had a midwife walk out on me twice, once when I threw up when I could have really used some help (told me she'd be back after I changed), another during the placenta delivery that took too long (literally threw off her gloves and stormed out). The latter came back with someone else not sure what kind of HCP she was and while the midwife kinda went on about how I wasn't a priority for the OR which was apparently very busy (there was nothing concerning yet other than it had now been over an hour), the other held my hand and was just very nice while I dealt with more awful contractions trying to get that out. I do wish that someone had discussed that with me afterwards, I never actually saw the placenta and didn't know that what happened was a possibility - I knew placentas could be an issue, but not like that -- and it wasn't until my fourth where I'd had the third stage injection delayed and so had more HCPs involved that I had someone discuss that I had an enlarged placenta (she remarked it was very enlarged, it was took big for the normal bag and had to sit on the table for a few minutes - it took up the whole thing) and that it was possible that I had that in the previous pregnancies where I had had problems passing the placenta (3 out of 4 deliveries, I had placenta issues).
Generally, I liked knowing what's going on/happened which some HCPs were better at than others, kindness, and sometimes some practical help.
