Best way to tell if newborn panther is eating

[Bonginator]

I have a newborn Panther who hatched a week ago. We have been feeding flightless fruit flies but really can't tell if he's eating any of them. We have seen him drinking but not eating yet.

Any suggestions to determine if he's eating? We want to make sure he is ok...

His color looks ok. Light brown and he's moving around the container a lot.

Look for poop. If he's pooping then he is eating.
