I breastfed my first for two years
Then I had a pituitary tumor make me very sick
The tumor and my pituitary gland was removed
Pituitary gland makes prolactin
Prolactin makes breast milk

I am now in the 3% of women who truly cannot breastfeed.
I can give my baby colostrum it comes from the placenta.
But no milk will come.
My second got five days colostrum then formula and donor EBM
