Thanks for this. I always feed her when they vaccinate her. It happened by accident actually. When they came to give her vitamin K injection just after she was born, I'd already started BFing her for the first time. The MW half told me off as she said that they liked to give the injection first. Anyway I said I didnt want to take her off as she'd latched on lovely so she did it while she was feeding - she didnt flinch. Again, by accident, she was BFing when they visited us at home the first time for he heel prick - again, not a muff. So I've just taken to doing it every time now.
I would say though that my sister said she did the same thing with my nephew and he was bottle fed. She would have a bottle ready and feed him while they did it or straight after and it worked the same for them too.
