I am currently BF'ing DS4 who is 4 weeks and it is going well, despite the mastitis I have got ATM. He has been gaining weight well (born 7lb14, 9lb11 on monday) but I keep having wobbles.
It might be him getting his flaming arms in the way and turning his head the wrong way whilst crying for a feed at 2am
or nothing at all, just me not in my comfort zone which, unfortunately (in my eyes), is FF. I really would love to BF him as long as possible but right now am on the edge of stopping so that I can be back on familiar ground.
I think part of me feels guilty for being more snappish with the other LO's as well, I can feed comfortably and one handed with a bottle - not so with BF with my SPD I find it hard to sit comfortably (I cannot feed lying down because of the size, shape and geography of my boobs). This means I can't do as much with them (the DC's) as we would like or need and so it goes on.
I know FF isn't poison, if things hadn't worked out I would not have felt guilty (as I have done before) so I have no problems with that.
Equally I know that BF is the absolute best I can do for DS4, and I knew it wouldn't be plain sailing at first so no shattered illusions there. I even asked DH not to let me just give up if things got a bit rough, but to remind me why I wanted to do this in the first place and let me moan if needed - which he has done last night brilliantly.
He got me to see that because I felt so unwell I was possibly not making a balanced decision and to wait before making a decision - DS is still feeding from both sides, so no worries there - I just needed to see the DR and get my medicine. ( BF being free helps him stay focussed)
So why am I posting? I think right now I just need reassuring that it's ok. Later I may need a slap 
Oh and the actual question here; my (older wiser) Dr said keep feeding from sore boob, the one who came to visit suggested otherwise... although she did say maybe only stop if it got worse when I pushed her. Instinct tells me to keep feeding but what would you suggest?
And finally for now, how do you know when BF is established? Are there signs? ( I know I'm not there yet, just curious)
