Thanks so much everyone, your replies have really put my mind at ease I am just a big baby and was really worried about the pain for bubs (my Mum told me that it was a really awful test and both my sisters howled and screamed and it was all very traumatic ) I will definitely be feeding him when it's done, it seems to be a good distractor!

Thanks again
It *used* to be a horrible ordeal; my daughers dad was particularly worried when we were about to have it done to DD because he remembers seeing his sister take the test (some 14 years ago now); the Dr took out a scalpel and slashed the bottom of her foot and there was blood everywhere, aparently (though perhaps the 8 year old mind does exagerrate lol).
