Cluster Feeding Still?

Maddy

My baby is 15 week and he seems to be cluster feeding again today. He has bet done that in weeks. I’m trying to figure out if he is just cluster feeding or if my supply is dropping. He now sleeps through the night and ever since he started to do that i can’t pump more then a few drops from either boob. Not sure what’s going on. Anyone else’s baby still cluster feeding?
