One thing I found with babies is that they are very nervous and very scared. They're new to the world and don't know anything about people yet -- so to them, you're a HUGE scary predator and they don't want to put themselves into a vulnerable position by eating with you around. I found that my hatchlings did best when I dropped the prey in, covered the front of the rack with a black towel, and shut the lights off in the room and left for 20 minutes. When I'd come back, the prey would be gone. This gives them darkness and privacy without any motion or anything to scare them. After a few meals like this, they start to feel more confident and will eat no matter what. Good luck!
