The best trick I ever learned about Ball Pythons (or any live animal for that matter, but especially BP's) is PATIENCE. Nothing happens overnight. Take a deep breath, perfect your husbandry, feed them appropriate meals, as everyone has advised you on, and enjoy them while they are small. Eventually they will grow into adults, and you'll wish they were small. The time eventually starts to fly by, and you wonder where it went.

That's the best advice that I can give that L've learned over the last 6 years.
