Wow, it looks so at home .
I have a tiny species of tree frog and they don't over eat much, but I noticed that once, Lily (my E. Johnstonei) ate a somewhat large cockroach and her belly was very round looking. She didn't eat for a whole day and sat on one of her vines.
Perhaps it's best to do it every other day, dropping in crickets I mean. They'll hunt what they need and the rest will live for when their hungry again. If you give too many, I think they'll gorge on them and won't hunt for them.
Just sprinkle a few and let them hunt for them and whatever is left over, they'll have to look for them.
Or as I recall reading somewhere here, try putting your crickets in a small glass bowl/container and let the frogs eat the necessary amount from there. Crickets can't grip the glass, so they can't climb/jump out. And this way you can control how much they get.
