Hi kbaby, as the others have said - don't worry - easier said than done, esp. with 1st I know. My 3 were all 'speed feeders' - 5 minutes on av - 10 max. They never went for 20 minutes. I'm sure some do, but don't worry if yours isn't 1 of them.
Re the feeding in daay, are you sure she's definitely hungry each time? I think it took me 3 babies before I really learnt what they wanted, but I think the temptation if to feed when they might be crying for another reason. Sure the feeding will often settle the crying, but might not have been why she was crying in the 1st place, iyswim. i know even with ds3 it took me a few weeks (dum or what) to realise he was tired at 7 - 10 o'clock every night when he was crying. All that jiggling and the poor soul just needed some peace & quiet & be in bed.
Just don't be a slave to the feeding, I bet it's often not the reason for the crying, so I wouldn't rush to feed when she starts to cry. With my 1st I was feeding him 13 times a day, so probably similar to you, and it was a killer. You'll get seriously exhausted & fed up.
Have you tried a book like Gina Ford. Very controversial I know, but I found her useful, especially as a 1st timer when used as a guide rather than a bible.
2 weeks is still very early though, and it will sort itself out. best of luck
