Growth Spurt or Day & Night confusion

So my LO has slept 6 hours straight at night for the last two weeks. He just turned 6 weeks and last two nights has woken up every 2 hours for a feed.

Three nights ago I also had to wake him during his 6 hour cycle to change a poop explosion and I’m worried interrupting his sleep now has somehow confused him? He has also been taking longer (2-3 hours) naps during day.

Is this just him cluster feeding because of a growth spurt? Or because I woke him during his most peaceful sleep and now he thinks he’s supposed to wake up at night?
