Cluster feed craziness

My little boy is 15 days old. When he is cluster feeding he is up for 1 1/2 - 2 1/2 hrs with 5-20 min breaks between each side. Is this normal? The feeding seems good but then he appears very over tired but before he reaches over tired if I try to put him down for bed he starts searching for food.

Just getting frustrated and want to be sure I am doing the right thing.

He slept from 11:15-3:25 and has been up feeding on and off now until 5:30 this morning! I’m going crazy. Just hoping it’s a phase and not just him?
