Baby turtles are mostly carnivorous like their parents. Sometimes they like to nibble on a piece of lettuce floating on top of the water. Feed them whenever they are hungry. Always wash your hands after handling any animal. Turtles will carry disease if they are kept in filthy conditions.
Turtles do best outdoors.
When the weather is warm, place them outdoors in a kiddy pool filled a little less than half with water. Add some floating pieces of driftwood to climb on and to hide under. Add water plants to hide under and also flower pots set on their sides. Birds will carry off small turtles so make sure the little creatures have a place to hide. Frogs are also known to eat hatchlings.
