When to move up in feeder size?

So, since I got my two babies together I really don't have much experience in feeding little ones. Right now their both 100 grams give or take 10 and their hammering rat pups like there's no tomorrow every five days. When should I feed a larger size and what would be the next size up?

Rat pups to rat weanlings. I usually put balls on a 7 days schedule when they get to be on small/medium rats roughly, there's no magical weight I go by when I decide to feed them less frequent. I do go by the 10-15% rule though when they're younger.

small/medium rat as in rats that are already wean? I'm feeding my close to 400gram balls weanlings right now on a 7 days schedule and they look hungry around the 4th day, wondering if i should feed them more frequently

Smalls are usually in the 50-80 gram range, so fully weaned yes. All of my larger snakes (500-1500) are all on larger smalls but too afraid of mediums to move up yet.
