@Sillysocks998 I actually forgot to mention that many women don't bother buying a pump at all! The emphasis should definitely be on direct feeding rather than pumping. Babies are (usually, with some exceptions such as tongue tie) much more efficient than a pump at removing milk from the breast. Breast pumps didn't even exist a century ago!
Try not to feel too daunted, I found the midwives and feeding assistants really helpful when I had issues feeding DS and there is help out there if you struggle, but it's more likely that it'll be straightforward and you'll have it figured out quite quickly!
I do recommend doing a breastfeeding class if you can (I attended one at my local hospital for free), as it is helpful to have someone talk through the basics and demonstrate positioning.
One thing worth mentioning (because I found it a bit of a shock) is that although it's "natural", breastfeeding can be very hard work at first (you and baby are both learning!) and it can be painful, but there is a massive pay off once established.
