Give them time to grow up a little bit. Cobalts are far, far, far from skittish. Mine are so bold I have to shoo them off the coco hut if I want to look under it. If Im gentle I can even pick it up move it over and they'll still be sitting on top of it. They would make great first dart frogs. Gotta remember all baby animals are born with the instinct to hide. Once they realize no one is trying to eat them they won't ever hide. I have my pair on my desk at a very busy loud office at an automotive body shop (yes MikeM670 you probably didn't see that one coming either). They don't care about the noise, the traffic or anything. They are always out front and moving around. They make for a great display frog for your living room or office.
