^this is generally true.
however midwifry students have to deliver 40 babies before they can qualify. my mum (a midwifry student mentor) says that it is very common for third year student to have to do extra night and day shifts to tot up their delivery score. she once told me of one nursing student who stayed in the hospital for 50hours straight because she only needed to deliver two more babies to qualify.
so yr 1 and 2 will be fine and yr 3, if your lucky, will be fine.... but the extra hours in 3rd year is not uncommon for a midwife.
also my mum has said that if midwifery students are flagging behind on deliveries (because lets face it you cannot decide when a baby will be born) they may place you on a big meternity ward, where they deliver 25-40 babys a day.... that always does the trick.lol.
