Dinny, contact the Head of Midwifery at your hospital. The midwife whom I talked to had not attended the birth. As far as I am aware, the first time she read my notes was when she was preparing for our meeting. As it was at the same hospital where I gave birth, she may I suppose have talked to the mws who looked after me, but I doubt it - I was looked after by at least 3 different sets of mws because of the shifts!.
If you are too far from the hospital in which you gave birth, then you could either ask for the notes yourself, in which case you'll probably have to pay a fee and maybe wait ages, or you could ask for your 'new' hospital to request the notes themselves. I would have thought that there would be no problem with that, after all, your previous pg and labour could be very relevant to your next/current one.
BTW, re tearing and stitches:
ds1 - 2nd deg, didn't heal, constant discomfort and some pain until restitched at 8m, but still some discomfort even after the repair.
Dd - 2nd deg but not as bad, healed perfectly, and, best of all, somehow sorted out the residual discomfort from ds1! No more pain.
Ds2 - 'graze', no stitches despite him being a whopper.
