hey sweetie
when i stopped breastfeeding my eldest i did it very quickly because he just wasn't able to suckle from the breast (he was still 2 and a half weeks prem when i stopped and wasn't thriving at all
) i made the decision to stop and then just stopped. I'd been expressing for weeks with very little stimulation from the baby to get my milk going so was drying up anyways....
With regards to the engorgement and pain... i found a warm shower was a life saver - i tried very hard not to touch my boobs at all and wore a firm bra for support - used cold savoy cabbage leaves when they got really hurty and then just allowed the milk to trickle out under the shower - this was over ten years ago and my memories are very very hazy hun but once i commited to bottle feeding there was no half way house for me.. get some paracetomol in.. i seem to remember enjoying a bottle of wine that night for the first time in months... i can't remember how long it took for it all to subside.. not long - it seemed to be really bad and awful and then it got better quite quickly
hope you feel better soon hun x x x x
