I hope you don't mind me posting on this thread as I did successfully breastfeed but I just wanted to voice support and say that I totally understand the sentiments expressed here.
I did not have any thoughts on breastfeeding until I became pregnant but then once I decided that I really wanted to breastfeed all I seemed to read/hear about during pregnancy were the negative points of breastfeeding, the pain and discomfort, what happens if your milk doesn't come in, thrush, mastitis, constant feeding, leaking, etc.
After DD was born I was almost afraid to try as I was convinced that I wouldn't be able to or wouldn't have enough milk as I had no colostrum/leaking during pregnancy. I approached it with a grim 'military-like' determination and it took many months before I was able to relax into it and become more confident.
I struggled with the latch for several days, spending literally hours in sweaty, anxious tears with a hungry, jaundiced DD hovering near the breast until a miraculous midwife sorted us out and gave me the confidence that yes, I could do it, despite what everyone else said, negative comments from 'helpful' family members, etc. I know I would have been very upset if it had not worked out and as I have tendency to dwell on/obsess about stuff I am sure that would have lingered on.
As it is I still have lingering feelings of inadequacy as after being induced 11 days post due date, my labour ended in an emergency c-section and I feel as though my body somehow failed to go through birth 'properly'. My point is I guess that we all have feelings of guilt/inadequacy about something. (I am currently feeling guilty for instance about getting impatient with DD who was pulling the phone out of the socket whilst I was on the phone to my boss earlier...) What I am trying to do though is to focus on the things I know I do well and accept that am not superwoman and no-one can be great at everything.
I hope that wasn't too long and that it makes sense to someone else other than me!
