- One-third (36%) of children have TVs in their bedrooms, ranging from 16% of children under 2, to 37% of 2- to 4-year-olds and 45% of 5- to 8-year-olds.
- According to a study of children at more than 60 schools, by the end of 4th grade, those kids who had attended academically-oriented preschools earned significantly lower grades than did those who had attended more progressive, “child-initiated” preschool classes, where the emphasis was on play.
- Toddlers 1-3 years old need 11-14 hours of sleep in a 24-hour period. At 18 mos. many toddlers go to one nap lasting 1-3 hours. Preschoolers 3-5 years old need 10-13 hours of sleep and most do not nap after 5 years of age. Children should never have TVs in their bedrooms.
