My son didn't sleep through the night until 4 months. At two weeks, it's too early. In fact, my doctor told me that for the first 2-3 weeks, I had to WAKE him up at least every 3-4 hours if he didn't wake on his own.
It's very hard. Sleep when you can. I know that I usually took 1-2 naps daily during those first weeks. Once the baby is older, you can start pumping and introducing a bottle, and your dh can take one of the night feedings. I had one friend who nursed her son at 10 pm. The dad took the 1 am feeding. She got the 4 am feeding, so she got about 5-6 hours sleep straight. I didn't do that, but my son usually only woke up 2x at night.
We didn't start the "cry it out" until about 7 months. He'd already been sleeping through, but started waking up again. At this point, your baby just isn't old enough to make it through, particularly if you are breastfeeding.
