Like Albert said, I would just clutter up the tank with plants and give it a bunch of hides. The size isn't necessarily the issue, its the big open spaces that will make a baby scared as open spaces usually equal a predator having easy pickins. And pretty much what the others said about covering 3 sides, no handling etc. I had Dottie in a 40g when she was only about 100g but I gave her 5 hides and those silk vines you buy from Michaels craft store and she was fine. Now shes just over 4' and I need to get her an AP T8 lol.
