I had a client who had to have a c/s due to placenta previa - she started bleeding and had to go in. But before she was in theatre, I asked the midwife for some test tubes and we were able to express loads of colostrum just in case something happened and they could feed the bub colostrum after the birth if needed. Luckily the midwife was very supportive, even enthusiastic that I asked and gave us a hand. I've seen bubs been given sugar water before and things like that, so we decided to be one step ahead and have something ready. Might be something you could organise too should it need to go down the path of c/s
