Foremilk / Hindmilk imbalance

Hi everyone. I'm pretty sure this is what we're dealing with. My boy is 5 weeks old and has all the symptoms below (although sometimes his poop is yellow not green). His poops are SO forceful and he'll often have like 6 in a row. He still poops over 10 times a day. He grunts and groans all night and is generally super uncomfortable/gassy (it seems). I also know I have an oversupply and forceful letdown.

Right now he'll drink for about 5 min per side each feed. Every 60 - 120 minutes.

We do:

Feed one side, diaper change / burp, feed other side

Would it be better to switch to:

Feed one side, diaper change/ burp, feed same side again? And just alternate breasts each feed? Would he get more Hindmilk that way?

Any other suggestions welcome!! I'd like some relief for him and a more peaceful sleep for us all 😊
