I had surgery when Riley was 4 months old, my anesthetist told me it was safe to bf straight after and I did and we had no hassles. Most of the anesthetic is breathed in so not passed on to the baby. I know some hospitals used to say to express the 1st feed after the op then throw it away but I had no problems at all, Riley wasn't even sleepy afterwards and I fed him as soon as I got out of the op. If she has any questions feel free to PM me.
