ffs. Maybe she CAN'T breastfeed ??
This really pisses me off, when I was pregnant with dd I was so sure I was going to breastfeed I didnt buy bottles, a sterilizer, milk, nada.
For some reason my milk didnt come through, it just didnt happen, no explanation for it I was dry as a bone.
The nurses had to give us some bottles of milk so we could take dd home.(christmas Baby)
I was devastated, and would have felt even worse if i'd had some idiot rambling on about breastfeeding, just to make me feel that little bit worse 
I succesfully fed ds for the first yr, no problems.
And if she has chosen to bottle feed because she has other children to deal with then that's her business!
