I'm happy to say all the midwives I dealt with (probably at least 60) with two babies were fine, mostly very professional, helpful and supportive, which is pretty good seeing as almost all of them had to get to grips with my complex notes having never met me before and figure out what they were meant to be doing. At least my notes had a list of scheduled appts and various other info pages included so I knew what was when.
I would say, apart from asking what level of knowledge someone has and then checking they've understood what you've told them, please don't make promises you can't keep, and if there is a problem with the service to you as a patient, apologise for it. My postnatal care the first time was shit. My complaint letter was fobbed off (admittedly the new head of midwives hadn't been in post at the time so little she could say). Second pregnancy triggered nightmares. Cue psych involvment to deal with PTSD.
It was hugely alleviated by a lovely MW I saw who got me to tell her about my neglect previously and said simply "That should not have happened. That neglect is totally wrong and should not have happened to you. I am very sorry. I know there were big problems back then and while I don't want to say we have no postnatal problems now, it is much much better - for starters instead of 80% bank staff on nights, we now only have around 10% who are mostly regulars. I hope you will find the service is much much better. I will put on your notes that you were badly let down last time and they had better be good this time."
And they were. Faultless care. Thing is it was probably a lack of care assistants rather than midwives who were the problem, but if you are given a named midwife at the time and have no clue who else is on the ward, its the MW who gets the blame. Equally I have no idea if MWs are responsible for someone strolling in at 6am announcing they are going to demo how to top and tail your baby (ds and I and my terp had finally got to sleep around 5am. Terp had no idea what the woman wanted. I just knew that ds and I needed sleep so got terp to relay 'fuck off'...) - but if MWs have any influence over schedules of the postnatal ward, actually not waking up sleeping mothers would be great!
Actually worst MW I had was when pushing with dd - she was perfectly OK, but tiny and had a dislocated shoulder, so totally useless at helping me into a good position. Don't MWs get sick pay?
Actually, probably summarises to "Dear MWs, please lobby your superiors as much as necessary to ensure you can do your jobs and other jobs involving pregnant/labouring/postnatal women also get done. THanks."
