Yes, it can be frozen. However, how will the process start since it is supply and demand. Will she have to start pumping in between feedings to increase her supply with baby not getting enough until it increases? What kind of a douche bag does this to his child?
Others do this without the difficulties that you imagine.
The kind that loves his child and has a right to visitation.
But of course we forget one thing
FATHERS HAVE NO RIGHTS.
One who loves it. Fathers should get as much time with children as mummy. Today especially.
My wife breast fed all 3 of our kids and also pumped between feedings. Our freezer was full of milk. It is no big deal. I could bottle feed the babies with thawed breast milk. We did this with each kid after the 6-month mark. The mom could easily comply.
She can feed the child what she pumps. She doesnt need to throw it away.
What kind of a douche bag denies a father the right to see his child?
Which part? Creating a child with someone who months later you can't work with to do what's in the best interest of the child? Creating a child with someone you aren't or won't live with? Creating a child who has to visit someone YOU are unwilling to visit?
The answer: BOTH of them!
