I supported a client who had to have a c/s due to a low lying placenta bleed. It wasn't super urgent as the bleeding wasn't gushing or anything, so we had some time while surgery was being set up, so I asked the midwife for a syringe and sterile jar and the mother expressed the colostrum with her hand and I slowly sucked in the colostrum with the syringe. We did this in case the babe was separated from her mother longer than need be and instead of them feeding the bub something else, they could feed it colostrum. We got a fair bit out and the c/s went well, so she was able to put the bub to the breast not long after. The bub still got the colostrum we expressed though. Liquid gold.
