Just to reassure your, my lo only took 3-4 oz until many months down the road. All lo's are different and not all need 6oz. My lo could barely handle 6oz at 12 months, so I wouldn't worry about the ounces too much.
After the dream feed, does your lo wake up at all in the middle of the night to feed?
How long have you been on a 3.5 hour EASY? What made you move to a 3.5 hour EASY?I always had to remind myself that all lo's are different and the numbers in the books are just averages. My lo couldn't handle a 4 hour EASY until about 5 months, didn't move to 2 naps until close to 11 months, so it all about following your specific lo.
I bet Vicki will have some great advice for you.
