How much and how frequently does your 3 month old eat?

Katie
My little one was taking as much as 6 oz when he was two months but we think he was over eatin to soothe his silent reflux.  He's 3 months now and only taking 3-4oz everything 3-4 hours and sometimes just isn't interested in the bottle.  Does that sound normal to you guys?  (He also has the dreaded daycare sniffles so that may have something to do with it.)
