OP: I haven't read the thread but I wanted to tell you that I 100% agree with you.
I was diagnosed with hashimoto's thyroiditis just before my first pregnancy and so was labelled "high risk" and told I had to have consultant led care. I didn't argue as it was my first pregnancy. The care should really have been called "junior doctor led care" and on each visit I had to see midwife / endo and obsetrician. Over the course of the pregnancy I saw only 2 endos but it was a different midwife and obstetrician each time, and each appointment took hours.
I managed to get signed back into midwife lead care for the last 6 weeks but it was stll a different midwife each time, and they were always running really late so was not great either.
In my second pregnancy I thought there must be a better way. I discussed the care I'd had in my first pregnancy with my lovely (male) GP and he agreed he'd see me for as many appointments as possible. He was very lovely - monitored my thyroid and everything else and in that pregnancy I went to the hospital twice for the scans and midwife once for a sweep right at the end.
In my third pregnancy it was a different GP but I still saw her as often as possible. Again turned down the consultant lead care, and again midwifes were totally useless eg not following up on blood tests, running super late, different person every time.
OP: In a totally ideal situation I'd see a midwife, but it would be the same one each time to build up relationship, based in the GP surgery, and there would be a GP, esperienced in pregnancy on standby at each clinic to pick up on things (another poster mentioned SPD) that might be problematic. I think the shared care model works well for people like me with minor medical issues (like hashimoto's) that don't actually need specialist input but are too medical for nurses.
BTW my dad is a retired GP and I wouldn't want to see him for ante-natal appointments but my gran (now dead) was a GP specialising in homebirths and midwifery (retired aged 70 in 1990) and I would have loved to have seen her. She delivered 3 generations of the same family.
to the poster re: the breech point - my friend's midwife told her the baby was head down, actually it was GP that spotted it was breech!
