It takes years to become a midwife, it cannot be done in a year or two, midwives are well qualified nurses who have gone on to specialise in midwifery, Even if a young girl starts a midwifery course combined with nursing that takes a while, and the midwifery would of course come last after nursing. I know of a few frum midwives in London and Jerusalem, they married young whilst training in nursing qualification and then went on to be midwives. Fantastic mothers too!
For me a prospective daughter-in-law with a midwifery qualification would be a real gem, someone following in the footsteps of Puah and Shifra, good on childcare knowlege and general healthcare, what an asset!!
