I teach sociology and politics at GCSE, A level and also on Access courses. An Access course is for people wanting to return to education after a gap. There students get funding because they have no level 3 qualification. You do have qualification so you may not qualify for an access course. However the point I want to make is that, the age of students is from 19 to around late 5Os early 60s . Although I have and still do, get older student my oldest being 83 she just wanted to prove she could do it. (They dont all get funding) There is an access to social care / nursing, which helps students get ready to apply for nursing, midwifery and social work.
I would say go for it, there is a shortage of midwives. However beware that this are is very underfunded and universities don’t take many students each year, its very hard to get into. They like you do have experience in form of some kind of voluntary work. This shows a commitment and determination, you nust show that you know how demanding the job is. The dropout rate in university for midwifes is high than the average . This has led to universities tending to select older women from what I have noticed.
Also if you get an interview don’t mention babies (they hate it) the focus is on the mothers care. Good luck Go for it .
