Based on the history given it looks like a demand feeding behaviour. What happens is after certain age babies start taking feeds on their demand, that means they manage their feed timings , sometimes can cluster feed every hourly for sometime and there after might go for a longer nap without sleep.
Having said that this can not be generalised to every baby, each baby has a different behaviour. Most important thing to do now is to keep a watch on number of times your baby passing the urine, and weight gain.
If both of these are satisfactory then you can have a reassurance for yourself.
