Cluster feeding

I’d love to hear what cluster feeding is like for others. With my first, he literally fed almost exactly on the hour for 24 hours straight (exhausting btw!) so it was really obvious when he was cluster feeding. My newborn is 2.5 weeks old and typically goes 2-2.5 hours between feedings. I’ll get the occasional 3 feedings an hour apart but that’s about it, and that’s not typical for my experience with cluster feeding. I feel like I should’ve already hit a cluster feeding but I don’t think I have so I was wondering what others experience with this. Help?
