Hi Becky,
It is awful, isn't it, Sorry to hear you are sore.
I'm 8 1/2 weeks in, and really struggled through the first few weeks (then I got thrush in my breasts, but that's another story).
Things that helped:
Taking painkillers. Paracetamol is ok. I also took codydramol because I had a c section.
Making sure the latch is right, though in my experience it can bloody well hurt even when you have a great latch. Signs of a bad latch are strangely shaped nipples when they come out, especially if they are flattened at the sides. If it feels like baby is rasping at the breast like a snail, unlatch, regroup and try again.
Counting slowly and doing labour breathing for the first minute or so (if it's not a latching problem, the pain will lessen after the first bit of the feed). I also did a bit (a lot) of biting down on muslins and curling my toes.
I found night feeds and early morning feeds worst. It helped me to have a cup of tea and a snack while I was feeding. I think my pain threshold is lower when I have low blood sugar.
It's great to distract yourself with tv etc, but make sure baby stays properly latched and doesn't slip back while you are not paying attention.
it really helped me to start expressing and build up a stock in the freezer for if you just can't face putting baby to your breast. MUCH better to do this than give formula as it helps to maintain your supply. I have only ad to resort to the frozen stuff once, but it really helps knowing it is there. If you do this, though, you must express too, after the feed of expressed milk, to maintain your supply.
Last of all, try to think about one feed at a time. Repeat "this is not forever". Just a tiny part of your life, but a vitally important part for your baby.
You are doing a really brilliant job. Hope some of this is helpful .
