Overfeeding my baby

Has anyone have any problems with their newborns overfeeding on formula/breastmilk? I understand there’s the whole cluster feeding issue but I’m concerned that my 1 month old baby is gorging himself after a feed. We have upped his feed from 2oz to 3oz. but he still asked for more afterwards. He eats every 2-2.5 hours. His tummy gets so big from all the eating. He also tends to spit up/vomit at least half of it after the feed.

How can we stop him from wanting more to feed? We’ve tried to give him the pacifier but he knows rite away that there’s no milk coming out of that and spits it out. He would cry bloody murder if we don’t feed him another one. He’s already gaining a decent amount of weight.

Any advice is greatly appreciated.
