All baby turtles will not eat anything for approx 7 days after leaving the shell. Mostly your baby turtle will be looking for good hiding spots. You should have your painted turtle in a habitat that has both a place to get into water and a place that has dry land. The water should never get too cold nor too hot. Likewise, the basking spot should not get too cold nor too hot. NEVER use hot rocks. Earth worms maybe ok for adult painted but you might want to look into buying some trout size earth worms. They are more a baby turtles size. Get a log hide from your local pet store and some aquatic plants for the water side of your turtles habitat. Make sure that you have an under the gravel (I prefer large stone for aquarium habitats) filter as turtles will often make "doo" when they hit warm water. Provide a true sun light source as your baby turtle will need both UVA and UVB to grow strong and healthy. Do not feed lettuce. There is no nutritional value. Do feed bits of tomatoes, any kind of squash, dandylion leaves, earth worms, trout worms, and frozen blood worms.
