No I don't feel guilty, if anything I realised I really did the best for myself and ds1 at the time!
sorry to bore anyone with this story again, but OP you may not have read this before so here goes.
With ds1, he was born Esection, he was knackered I was knackered (to the point when they were giving me my spinal I thought I was going to die with tiredness and did not care!! DS1 had jaundice, I tried to BF, but the support on the ward was mixed from staff.. one in particular was very negative and I pestered all the time for help on checking he was latching on ok etc etc. However he got sleepier and harder to feed and then it took another nurse from another ward to see him and tell the MW to move him to transitional care, he was so nothing like with the jaundice he nearly needed a blood transfusion and whilst I kept expressing he needed to gain weight and we used formula as he kept pulling the tube out of his nose that had been feeding him.
When we left hospital he started to lose weight again, he cried all the time, he was stuck on my boob, I was still knackered from my section trying to recover and then I decided enough was enough to ensure we both thrived formula was to be used (had no outside support as bf counsellor in area useless) From that moment things improved greatly.. now at nearly 5yrs ds1 has been healthy, he was a healthy babe too.
Now 4 wks ago I had ds2.. I really wanted to give bf a better chance to work this time, so bought a book, started a thread here that bf can work after an elective section, and mentally psyched myself up.. hmm, still wasn't prepared for all the initial pain/long nights, no sleep, bout of mastitis not long ago.. but it works (though still need to refine the skill and am NOT guilty that ds1 was not BF.. why.. because I understand WHY it did not work first time around, like I say did the best I could with no support and at the end of the day I look at ds1 now and have no complaints.. he always has been in good health, he is soo easy going and was a baby too, and what happened happened, no need to give myself a hard time and you don't need to either.
Infact I joke to DH we have an experiment going on bottlefed vs bf babe, but of course it could never be a true experiment because of the variable of their own unique personality! I'd say give it a go. I was also lucky because the hospital support this time around (different hosp) was FANTASTIC and I'd also paid for an amenity room, I think I might have given in to bottles if I hadn't because I had one hell of a noisy babe!!
I don't feel at 4 weeks I have the whole thing cracked but it has been hard and only very recently has things looked brighter.
All the best.. and sorry for the essay
