To piggy back on what @chelli said; you can , however, cause a lower supply by supplementing. Remember, your baby and body work together as a team. Your baby tells your body what it needs and your body jumps into action.

His eat sounds normal for his age. They nurse 8-12 a day at his age. As long as your get 5-6 wet diapers a day don't worry. You can't nurse to often or to little milk is supply in demand your breast will know when to produce for him.

My baby cluster feeds she bottle fed omg it’s so hard on us no sleep

If he's wetting enough diapers a day, he's getting enough.

He wants to cluster feed. Also breast milk doesn't have as many calories in it as formula does, so he will want to eat more often regardless.
