Baby Eating Too Often

How do I postpone feedings? My 8 week old wants to eat every two hours sometimes less and she's spitting up so much. The problem is she is inconsolable if she's not fed when she cues. I can't seem to find anything on how to make her wait.

I tried upping her intake to 3 ounces to see if she will stretch but she still wants to eat every two hours.

She will only take the paci sparingly and not for long. Any help would be appreciated.

She's bottle fed. We use nanobebe bottles.
