Basically, the bottom line is that colic is caused by pain that isn't easily soothed by pretty much anything, but often times babies aren't in pain, they just need to be held and be close to you. If after feeding at 9/10pm, you sat in a rocking chair with baby on your chest and rocked, would she still cry until 1am?
If the answer is yes, I'd look into seeing if you can find ways to eliminate the discomfort (we found gripe water worked well for reflux and for constipation and many people use it for colic). If holding baby on your chest and rocking for 4 hours means she stops crying and sleeps, then I would say it's just normal and not colic. I think there can be an expectation that all babies just sleep happily on their own from birth, but most don't and it can lead you to worry something is 'wrong' rather than just 'normal'. If rocking her in a moses basket to try to settle her isn't working even though she's fed, clean, etc., then find other ways and see if they work. If they do, you just have to find a way to do them until this period passes and it all gets easier. It doesn't seem like it will and right now it feels like nothing will every feel manageable, but it will! I promise!
For us what worked is using a wrap, co-sleeping and just taking shifts during the night comforting our daughter. It seems overwhelming, but if you think of the first 8 weeks of baby's life as a time when you have to do anything that works so you can cope, it makes it seem more temporary and more manageable. We put our daughter in a wrap in the early evenings, from roughly 7pm until her next feed, and I went upstairs and slept. My husband would bring her up for a feed at around 10ish when she woke up and would often put her back in the wrap until her next feed around 1am. He watched a lot of films those first few weeks! It meant I got some sleep, so that after about 1am, I could take over. We co-slept, and often I just sat in the rocking chair or bed (awake) with her sleeping on my chest. I didn't get much sleep the second half of the night but because I got about 4 hours earlier in the evening, it was doable. This sounds intense, but I can't stress how temporary it is. It won't last forever. She actually started to occasionally STTN without a feed a few nights from about 8 weeks and even when she didn't (which was most of the time), she would wake, have a feed, and go back to sleep. I would get full nights of (interrupted) sleep, but didn't need to be awake for any length of time. It really doesn't last forever! Do what you need to do now. Sleep during the day. Forget Facebook (or BnB). Forget doing the dishes or having visitors over. Sleep. Go to bed in the early evening when she does so you can get a couple good hours of sleep before she wakes at 9-10pm. You'll have a life back in the evenings in a few more weeks. You'll be able to make dinner and clean and even drink a glass of wine and relax. But the period from birth to 6-8 weeks is intense. Make just functioning a priority. Everything else can wait. Life really will feel more normal again soon.
