Morning all!! 
Happy Wednesday! (Wednesday is the start of my "new" pregnancy week so Im always happy when it comes - exactly 32 weeks today)
Almighty this was so, so true for me too "I feel I bonded much better with my other 2 DC's than my first." (except I only have one "other" dc right now).
I gave myself a terrible hard time over my "failings" with dd and if Im honest, really, really did not enjoy the first couple of months of her life because of that. Depression was definately aggrivated by the whole thing for me personally and Im annoyed with myself as I cant get the time back.
That said, at least I learned a valued lesson and have to admit that the first few months of ds's life were so lovely for us all - happy and relaxed - we really enjoyed them!.
Reading it back and your story sounds so similiar to mine that its scary. I did try relactation after giving up initially as the guilt was all consuming which, if Im honest, just made things worse. All I can remember is me crying, dd crying and dh begging me to just give her a bottle. I think for about a year and half though, if anyone as much as mentioned breastfeeding, I would burst into tears (which was absolutely mortifying!!
).
Anyway, Im not saying all this to put anyone off in the slightest, I would just beg anyone else not to be so damn hard on themselves - I agree with everyone who has said try it - if it doesnt work, it doesnt - enjoy your baby and dont go and do what I did, you'll feel guilty about enough in motherhood.
That said, I really dont want to appear anti breast feeding and dont want to scare any first timers - this is not typical and I honestly have seen, first hand, what a fabulous experience breasfeeding can be for many people. The benefits to both mother and baby are huge as we all know and I know so many absolutely adore the whole experience!!. I think sasamaxx gives some really fantastic, helpful and positive advice (from an experience bfeeder too!!!)
