DON'T handle it unless it's to move it while cleaning it's enclosure or to feed it in a seperate enclosure if you wish to do so.
Keep it in a small sweater box with a hide, water dish, and suitable substrate. Cypress mulch, Sphagnum moss, newspaper, paper towels work well. If you use one of the more natural substrates mentioned and want to prevent the snake from ingesting any accidently, feed the snake in a seperate, covered, container. Keep the temps at mid to high 70's on the cool end and mid 80's on the warm end. Keep the humidity level moderate and make sure you up it when the snake is preparing to shed.
Continue to feed the snake whatever it was being fed by whom ever produced the snake. Remember, these snakes cannot take food items that are much larger than their heads and will most likely become intimidated and not eat if they food item is too big, so offer small items and let it eat in privacy.
The most important thing is to NOT over handle the snake and NOT to watch it while it's feeding.
Give it some time and when the snake is about approx. 2 1/2 - 3 feet long you can interact with it more.
They are very sensitive when they are babies and juvies and you can throw off their feeding habits and cause them other undue stress by giving them too much attention at this age. Some snakes will actually regurge their meals if disturbed.
Where did you get the "03" YT???
I look forward to seeing pictures.
Good luck!
