They eat a lot in the summer, and yes, they do sometimes get chubby. But as long as you're not force-feeding her or pounding--and you'd know if you were--as long as she still has a good appetite, you should let her eat. Especially at her age and size. Hatchlings are usually hungry! And you really don't know if she's going to go off feed this winter, or for how long.
I had a snake refuse food for 5 months, and go from 800+ grams to 600 grams. Which is perfectly normal, but that kind of weight loss would clearly be dangerous for a snake under 400 grams. So if she's hungry, I say let her eat.
(Since she's already eating two items per meal, I think the first thing to try is leading with a mouse to get her started, and then offering a rat when she starts looking around for dessert. If she's difficult, you can also let her go a few extra days between meals, to see if hunger makes the rat more appetizing.)
