Don’t worry OP you’re not going wrong - i had a section and really struggled to get baby to take the breast and latch on properly for the first few days.
Google different feeding positions, initially the lying down in bed one with DS lying down next to me was the easiest and most relaxed for both of us.
With a section sometimes your milk can be a bit delayed coming in, mine came through on day 5. Be warned, when it does you can feel really weepy and even a bit fluey.
Colostrum is all he needs at the moment he has a tummy the size of a marble and colostrum is like liquid gold. Just keep an eye on nappies - if he’s not wetting nappies then give your midwife, health visitor or GP a call as that’s when you know he’s not getting anything/enough and could be dehydrated.
Are you still in hospital or at home now? Usually they don’t let you out until they’re happy you can feed baby and they’ve had two wet and one dirty nappy.
La Leche League is a brilliant resource as other posters have said, definitely look it up.
Breastfeeding can be really hard - especially in the early days and weeks, we’ve only just really clicked with it in the last week and a half and DS is four weeks old. Don’t forget baby is learning along with you - so it’s a bit of trial and error between the both of you and he might not latch on easily himself initially.
Keep at it though, if you really want to BF, but make sure you ask for help if you need it
