I formula fed DC1 and I'm proud of it. My first baby and I managed to keep him alive when prior to that I was so crap that I killed every plant I ever owned, even the ones I remembered to look after died. So yes, huge pride that I fed my baby and kept him going, not just going but thriving.
DC2 I attempted breastfeeding but switched to mixed feeding within a week and fully to formula by eight weeks. Proud of that too. I tried it, it didn't work particularly well for any us, so I made the decision to stop. I'm proud of myself for trying and proud of myself for recognising that it wasn't right for me or for that particular baby.
DC3 has been breastfed from day one, currently 15mo and still going. I'm proud of myself for that one too, although luck (that he fed well) and stubbornness have played their parts.
I've never felt any overt pressure either way, I've had random comments and remarks but I tend not to listen to them. People will always have something to say about what others will feed their baby but so long as it's not piss or poison, who cares?
Also I didn't think Woonerism was being at all smug or dismissive of anyone, it was awful the way she was instantly jumped on by some posters for absolutely no reason.
