Diva I totally understand as I had issues feeding DS for multiple reasons (including the fact that my nipples are apparently unsuitable for breastfeeding - who knew that was a thing?!). I battled with it for a month before introducing some formula - I ended up combination feeding and slowly phasing out the breast feeds until he was 5 months. He had jaundice shortly after birth, which meant he didn't have the right cues to feed so just wouldn't latch on at all, I had mastitis three times, which interfered with my supply, and I had the most painful cracked and bleeding nipples. DS would feed for an hour and still be hungry, I was utterly miserable and I genuinely think I'd have ended up with PND if I'd continued to breastfeed exclusively.
I do intend to try and breastfeed again this time, but I'm going to be open minded about it and not beat myself up if it just doesn't work. That said, i know a lot more about how to establish a good latch this time round, and where to get support if I need it, so I'm hopeful I'll be able to at least combination feed successfully.
I would never judge another mum for formula feeding from birth though, I do think breastfeeding has lots of benefits, but it's hard work and not for everyone, and DS has done just fine on formula!
