I agree with PZ everyone asks me about DD sleep. Then when I say she sleeps 6-8 hours then wakes for a feed and sleeps another 4 everyone jumps all over it by saying it won't last. Now when people ask, which is the first thing everyone asks for some reason I just say yeah she's pretty good and leave it at that.
We have had a few shocker nights but not many and I so take my hat off to those mummas who get through that every night.
