Hello,
I was always of the very laidback approach when I was pregnant and always said I would give it a go but, not put pressure on myself if she couldn't latch etc and just bottle feed. Luckily for me DD (now 2yo) latched straight away in the hospital.
Don't get me wrong... you get sore but, mine wasn't a horror story. I loved breastfeeding but, always knew I wanted to combi feed and so, we introduced some bottle feeds after about 4 months. It helped so much with the lack of sleep and my mood when DH could share the feeds with me.
I actually didn't realise but, DD had a very slight tongue tie which meant, the HVs and midwives kept telling me she wasn't latching properly. She was feeding fine and gaining weight but, I do remember feeling very stressed about not getting the approach cock-on at the time. Looking back, it was only resulting in my own discomfort which, after a few weeks of having your boobs gnawed at, you get used to it.
I would like to believe that my laid back approach meant that baby latched straight away and we avoided any great complications but, I know that would be incredibly naive. I do think it helped with my mindset towards it though!
Oh and luckily for me, never got mastitis! And Lanolin cream is the bees for cracked nipples.
Good luck OP :) X
