If you have a baby sling try carrying her in that during the day. At less than two weeks old I wouldn't be expecting a full nights sleep yet! She's still tiny and needs almost constant contact with the one person she's only ever known. It is hard work but I promise it does get better! One suggestion I'd give is try co-sleeping with her. Since your LO is ebf maybe try sidecar-ing the cot to your bed. If the base of the cot is on the same level as your bed this is easy to do simply by removing one side of the cot and pushing it right up to the side of your bed. I did this with my youngest and tied the cot to the bed frame to stop it moving too much. Any gaps can be filled with a tightly rolled sheet put the opposite side (push the cot mattress right up to the edge of your mattress - less chance of gapping) Having a cot sidecar-ed to the bed like this means you can easily feed you LO while she stays in her cot. This way you both can get some sleep (you get more sleep this way than you might think!)
During the day, if you've got her in a sling (try a moby wrap, they re AMAZING!) you'll be keeping her close to you and, depending on the wrap style, also more upright. This will help her digestion and, as everyone knows, anything lighter than its surroundings generally goes up! (Expect loads of baby burping if she does suffer with gas a lot!) Also, as she's constantly next to you, she'll relax more and that can only be a good thing.
If you're still suffering with problems speak to a LLL group, they should be able to help a lot more. There may be things in your diet that are making gas pains worse or you may want to try different feeding positions, the only way to work this out is trial and error. You're at the start of a journey that you and your daughter are taking, don't be hard on yourself, you're both still learning, try to relax, as for help from family and friends and enjoy your babymoon - you've waited long enough for it!
