Hi I'm a current 2nd year stmw. It's my 2nd degree and prior to starting midwifery worked in early years/health visiting.
I don't have any DC but do have a mortgage and bills and found leaving my full time, secure NHS job very daunting! I also have a supportive partner but still manage to run my car and pay 50% towards all bills. It is manageable.
Lots of people on my course have kids, they just have to be more organised.
Different uni's do things differently. Where will you be applying? Where I am we do blocks of placement that usually last 4 weeks and blocks in uni which are usually 3 weeks. A week in uni is 1.5 days physically in uni in the simulation suites and meeting with our tutor groups and 2 days of live lectures online from home (similar to zoom). Then 1.5 days off/study days.
Then a week of placement kind of depends where you are. Community is 8-4 Monday to Friday but you can also go on call for home births if you choose to. Hospital shifts are usually 3 long days 7am-8pm or 3 night shifts 19:45-07:15.
Other uni's do it different and do 2 days in placement, 2 days in uni, 1 study days and that just continues all year.
If you have any more questions I'd be happy to answer.
Be warned, it's not all sunshine and rainbows and midwifery is particularly awful at the moment. Only do it if you really, really want to.
