NAH. Give her time. She may change her mind after giving birth. Right now she has a lot going on in her mind, especially with all of the hormones raging through her - which is no joke. If she doesn't change her mind, respect that - but ask that she pump, as this will help out some - especially when it comes to breast pain (from what I've been told). However if she doesn't, don't freak out - the baby will still be OK as breastfeeding isn't the only way to bond.

My little sister initially didn't want to breast feed but ended up realizing how much she actually wanted to when she discovered that her daughter wasn't strong enough to breast feed, so she ended up having to bottle feed her from formula and pumped breast milk.
