I feed on demand, and have noticed that the length if time between feeds is increasing at last. However at the moment, lo is asleep. She had her last feed at 8.26am. It is now 12.45pm. This seems ridiculously long, not to mention unusual. In the daytime 2 1/2 hours is more usual. As I feed on demand, I guess she is fine so I shouldn't worry, but I'd be interested to know how long you Los go between feeds. She is 15 + 4, 15lb 3oz and thriving!
