2 week old sleep between feeds

Caysi

Our daughter is just hit two weeks old and we have been feeding her every 3 hours woth the exception of her cluster feeding like crazy the last two days. Her birth weight was 6lbs and she's now 6lbs 8oz. I've read to not let them go more than 3 hours without eating but I've also read that at night (once they reach their birth weight again) that it's okay to just let them sleep until they wake up to eat or at the most 4-5 hours at night.

I'm curious as to what other people chose to do and how it worked for them... because I am exhausted and could certainly use the extra 45 minutes at night.
