It would depend on what she had done in her 3 years. I chose my student mw due to her research into breastfeeding and having had homebirths. She was absolutely awesome at the birth, and my midwife only arrived just before baby. However, the experience of my midwife was evident when i had some issues post birth. The student was only starting 2nd year at that time, so i am sure she would have learnt much in that time. I know my birth helped expand her knowledge.

If she had been working for 3 years and quite active then i would be more comfortable than if she had been more quiet.
