Is it bad to use someone else's breast milk?

@khaliawhite165, I've donated twice to the NICU.

thanks @cubanese @mommasaurus @m8626 i'm a diabetic and I wanna breast feed and my doctor's keep telling me my blood sugar could affect the baby

I have a donor that gives me her milk. I can't make enough and my son would scream bloody murder when he was in formula! He does just fine! An upset belly here and again but who doesn't?!

I don't think so, I've heard of women donating it..
