Your baby should be active, as they get older they tend to be more slug like.

Sluggish behavior can mean parasites or just that your temps are off- or you know the drill, the half million things that can be wrong with your herp if...

I would look around the eye really carefully, sometimes they will retain shed around their eyelid. Or if it's a baby it could very well be in shed and bugging him/her.

Double check your temps and all that good stuff.

How's the appetite?
And of course, how are the BMs?
