Anyone else going through cluster feeding?

Tavia

My LO one is 3 weeks old (my first baby). And since delivery I was blessed with a good eater and thankfully breastfeeding has been a breeze. But now he doesn’t seem to stop. I feel like he is eating every hour or less, and long sessions. I don’t have a problem with my supply and he is gaining reallyyyy well. Will this growth spurt pass? I hate to admit it’s exhausting.
