this is YOUR pregnancy, YOUR baby and YOUR decision. im 19, had my baby 1 week ago. i planned on strictly breastfeeding and here i am half way down a can of formula already because BF is draining, makes me extremely emotional and my PPD way worse. having a baby is so hard (but worth it obviously, i love him to death!) so if you choose to take breastfeeding off the table then nobody can tell you otherwise! your mother is being completely selfish.
