Bottle Feeding Question

Katherine • Mommy to a loving baby boy ❤️👶🏻 // NYC 🏙

I have a 2 month old who has been drinking 4 ounces for a few weeks now. And suddenly, when he finished the bottle he seems like he still wants more. Even after burping in between and after. Then I place the pacifier in his mouth and he begins to suck it like if it’s going to run away from him. What should I do? Do I try adding another half? Or should I just let it be to not make him spit up too much for his tiny stomach?
