You can put a baby in there no problem. Just get lots of ground cover. I use plastic vines and plants from the craft stores. The problem comes when trying to find the baby and spot cleaning, not really a problem just can be time consuming trying to find everything.
Also make sure you disinfect the enclosure very well before putting in your decorations and snake.
