Four hours of sleeping bliss

Last night, the strangest thing happened.  Eli went to sleep around 11pm.  Dave and I woke up, naturally, at 2am.  But, alas, there was no crying or fussing.  I thought, "Should I wake Eli?? Does he need to eat??"  I thought better and left him alone.  Wonderfully, I was able to go back to sleep until 3am.  Then, I had to feed Eli.  But, 4 sweet hours of sleep.....  And, then, he went back to sleep for 3 hours more!  Overall, I only had to get up once to feed him last night!!  Woo hoo!!  Let's hope this continues....
