But using the eccentricity of the orbits as well, the Earth's distance is 1.0Â±0.01672 AU, while Venus's distance is 0.7233x(1Â±0.00679) AU.
How Many Hours of Sleep Does a Toddler Need? By the time a baby becomes a toddler, she will need 10 to 14 hours of sleep per day. This includes one nap (after 18 months, naps are reduced from two to one) that lasts about one to three hours. Keeping these numbers in mind, a toddler will normally sleep 10 hours or more per night.
As he gets older, your child will probably stop napping and start doing all of his sleeping at night. Children in daycare and preschool still need about 11 hours of sleep a night, but that amount will gradually decrease. By the time he's a teenager, your child will need only about nine or 10 hours of sleep per night.
