Probably. If it gets hungry enough then it will eat. May I ask why you are switching to mealworms though?
We are feeding all of our hatchlings baby crickets. They love them! They don't even pay any attention at all to mealworms b/c they don't move enough. It's like they don't even see them. Perhaps that's why your baby doesn't show much interest? May just need something that actually moves. lol
