It's going to be about ten days before he sheds. Keep him in a simple, humid set up until he sheds. Make sure he has a water bowl. After all the babies shed, they will need to be set up individually. less is more with the babies. Mine go in a shoe box rack with aspen bedding, a hide box, and a water bowl. You can give him a few days to settle in after that, then try offering him food (check to make sure his "belly button" is completely healed up). Some people offer rat pinks as a first meal, some offer mouse hoppers or small adults. It seems to depend on individual preference of the breeder, feeder availability, and size of the snake.
If the snake doesn't eat right away, remove the food item, and wait another week. You're going to be tempted to offer the baby food again the next day or two. I was when I had my first clutch, and all I did was stress out the little albino I was trying to feed. As long as they're at the proper temps and have a nice secure hide box, a healthy baby will eat when it's ready. Wait a full week to offer food again if it doesn't eat the first time. If it consistently refuses on type of prey, try another. As far as the drinking, they know instinctively that they need to drink, you won't need to aid him along in that.
