Instead of offering your own BM.. I would stress the importance of the anti bodies in the first few days and encourage her to consider expressing to give her LO the best chance of fighting any infections early on in life. But if you were my closest friend, and you offered my baby YOUR breast milk.. I would be offended yes. Dont take that the wrong way.. we all get that you are trying to help but thats not the way to go about it I dont think.
