Why does it annoy me?

I have had a couple of friends/acquaintances lately who have breastfed for short periods but then changed to formula. Both have said "their milk just dried up". I trying to work out why it annoys me so much. I think i wish they would just say 'i chose to FF'. Maybe it's about the spreading of misinformation, maybe it's cos i wish they were given better information, maybe it's cos i want to share an experience, maybe i'm jealous cos of the freedom FF can offer in some circumstances. One of the women was so chuffed at week 2 cos she was expressing and her DH was doing the night feeds and then she could sleep through. Maybe i should have said more, i certainly thought at the time that that was going to damage her supply. The other woman was sure she was going to have problems cos her Mum did, but didn't want to educate herself on BFing before bub was here cos she didnt want to stress herself.

I am supportive of women to choose what works for them, i think it's that their choices don't sound educated, and now they are propogating the theory that milk just dries up and therefore they had no choice.
