He slept thru the night!!!!! FINALLY!!!

So I am 7 1/2 months in and my son slept TWO NIGHTS IN A ROW through the night. Should I even attempt to get excited and think that he has taken a turn in his sleeping habits? Or is this just a fluke? I really hope he will begin sleeping thru the night every night. That would be great. Of course I was up every few hours checking on him. haha!
