My boys liked to nurse a little more often than the pp's. They both nursed every 2 hours during the day with maybe 1 or 2, 4 hour stretches at night at 3 mos....well, DS#1 had longer stretches at night, maybe 5-6 hours, but DS#2 didn't.
They both nursed every 2 hours clockwork during the day though. DS#1 started going every 3-4 hours at about 7-8 mos., and DS#2 was 12 mos. old before he went longer than every 2 hours during the daylight hours.
There's a wide variety of what's considered normal though.
