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.
Infants and Children. According to the Mayo Clinic, infants often sleep for up to 16 hours each day. Preschoolers should get about 11 hours of sleep each night, and children under the age of 13 should get about 10 hours of sleep a night. Teenagers should get nine hours of sleep a night. Kids Health from Nemours notes that getting enough sleep is critical for children because lack of sleep may affect their growth rate.
