Is it a phase, just a cluster feed or a leap?

So my little one is 1 month old today. A few days ago I had my first rough night with him where he wouldn’t allow me to put him down for at least 8 hours straight (I finally had him down around 4am). After that he’s been sleeping really well (2.5 hours plus) until last night where he would only last in his bassinet for an hour or so tops and it’s continued throughout the day (except for one good nap this morning) I always feed him when he wakes, a few times I’ve noticed hunger cues but I do it routinely anyway and more so just to get him back to sleep. Is this just a cluster feed, another growth spurt or his first leap?
