As a midwife myself I know from experiance that age is irrelivant both during training and once qualified. Your abiliy to care for women is dependant on your personality rather than age. The main things to consider as a mature student is any commitments/responsibilities you may already have, as midwifery courses are fulltime, demanding courses requiring both academic and practical assesments which include you working shifts(nights & weekends!) so financial and childcare issues should be considered carefully before you apply as you don't get paid for the courses. If you are serious about applying then very good luck, it's a wonderful profession (most of the time!).
