My 2 week old sleeps A LOT through the night - Most nights I have woken her to feed her after about 6/7 hrs but last night I left her to wake up on her own and she slept for 8.5 hrs.
The only reason I was waking her was because the midwives in the hospital said a newborn shouldn't really go longer than 6 hours between feeds, however, my friend has said that you should never wake a sleeping baby. It takes a lot to wake her up and usually takes me about 10 minutes to get her awake enough to feed. She doesn't particularly like being woken up either!
She was 2 weeks late (I'm not sure if that makes any difference!) and at 2 weeks old is usually awake quite a lot of the day (unless we're out and about) and at the moment is cluster feeding almost constantly morning and afternoon, with a couple of hours sleep in between.
This is (obviously) my 1st baby and I don't have a clue if it's too early for her to be sleeping this much at night and awake this much during the day.
ANY ADVICE OR THOUGHTS WOULD BE GREATLY APPRECIATED - I THINK I'M GOING MAD GOING OVER ALL THE PROS AND CONS IN MY HEAD!!! 
PS - I know I shouldn't complain about this and believe me I'm not - I just want to make sure she's OK sleeping this much, and that I'm not causing her any problems / feeding her too little!
