Your baby will probably be able to roll over when he's about six months or seven months, when his neck and arm muscles are strong enough. Some babies manage to roll over as early as three months, but other babies take longer than seven months. Your baby may take you by surprise by suddenly getting the hang of rolling over. This is why it is so important never to leave your baby unattended when changing his nappy on a raised surface.
The box turtle is the only species that spends most of its life on land and hibernates in the soil; the rest hibernate underwater. Many turtles have very long lifespans! Box turtles can live well over 100 years and other turtles like the spotted turtle can live over 50 years. Because turtles live so long, it is not so important that they produce many offspring every year. In fact, most turtle eggs or the hatchlings are eaten by birds, foxes, or other predators.
They are adaptable reptiles that can live in a wide variety of environments, which is the reason they are found all over the continent. In the wild, it is estimated that painted turtles can live as long as 40 years, though that figure is not common. With the risk of predators and illness, life span in the wild can be only a quarter that length. When the threats of predators and communicable disease are removed, a painted turtle can live quite a long life in captivity. A typical life span range for a pet painted turtle is 15 to 25 years with proper care. Note that these animals are naturally wild, so their life spans will be significantly shorter if they are confined to a limited habitat or are not properly nourished.
