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.
The experts unanimously agree on the average child's need to nap and on a napping schedule: Newborns sleep as much and as long as they need to. Between 4 and 12 months, babies move to two naps a day, one in the morning and one in the afternoon, each ranging from 20 minutes to three hours.In their second year, most toddlers go down for one two-hour nap in the middle of the day, and by their third birthdays, some will have given up naps entirely.razelton's view. At this age it's fine to give up naps entirely if your toddler doesn't need or want one. If he does still need a rest during the day, make sure it's not after 3 p.m., as that will break up his activity cycle and cut down on his need for sleep at night.
