I did a ton of reading as I was being induced at 37 weeks & really wanted to breastfeed. We're still going at year which is good as he has CMPA.
Most things I read was that it can take up to 8 weeks to get your supply established & get used to breastfeeding.
Your nipples will be sore in the beginning no matter what the midwife says, my friends warned me of this.
I saw a lactation consultant in hospital & midwives checked his latch which really helped me.
Also looking at different positions, my friend took her pregnant friend to a breastfeeding clinic before she gave birth & said she found it really helpful if that's an idea for you?
Lanisoh & breast pads are your friends.
Cluster feeding is a massive shock & sometimes you're just like what?
He fed for 7 hours one day at 8 weeks old so I took him to Asda just to give my boobs a break & someone said "Aww baby!"
Me - "What baby?"
He was there in front of me just so out of it from cluster feeding.
When cluster feeding get everything to hand, I had Netflix & channel 4 stuff, 2 litre bottles filled with squash & fruit, biscuits, chocolate, just everything.
& definitely drink loads of water as in the beginning your mouth goes so dry.
Good luck! Lots of skin to skin in the beginning helped us too, on the second day after birth my milk came in but I know it varies.
Also breastfed babies can go days without pooing. I didn't know this & finding it out definitely helped.
