When to talk to a doctor: If your child is not meeting the milestones for their age, has lost skills they once had, or you are worried about how they play, learn, speak, act or move, talk with your child's doctor. Don't wait: acting early can make a real difference.CDC · Concerned about your child's development? ↗

The research behind it

Start with the finding, then check the study type, source and limits. We select research by topic; a programme’s overall effect does not establish the effect of each activity.
  • In a study of 4- to 6-year-olds, the number of back-and-forth conversational turns with adults predicted activity in language areas of the brain better than the number of words children heard.

    Single-time studyRomeo et al., Psychological Science, 2018Study details
  • For children aged 1 to 8, play with gentle adult guidance did better than direct teaching on early maths, shapes and switching between tasks, and better than free play on spatial words. Other outcomes showed no difference.

    Meta-analysisSkene et al., Child Development, 2022Study details
  • A meta-analysis of 42 studies. More screen use was linked to weaker language skills, while co-viewing with an adult and better-quality programmes were linked to stronger skills.

    Meta-analysisMadigan et al., JAMA Pediatrics, 2020Study details
  • A review of 49 studies covering 50 interventions and 23,098 participants aged 2–17 found that several approaches can support self-regulation. Programmes and outcome measures differed substantially.

    Meta-analysisPandey A, Hale D, Das S, Goddings AL, Blakemore SJ, Viner RM, 2018Study details
  • Following about 2,400 children, more screen time at 2 and 3 years was linked to poorer developmental screening results a year or more later.

    Long-term cohort studyMadigan et al., JAMA Pediatrics, 2019Study details
  • 9-month-old infants learned Mandarin speech sounds from live sessions with a person, but not from the same material shown on video or audio.

    ExperimentKuhl, Tsao & Liu, PNAS, 2003Study details
  • Meta-analyses of 75 studies found spanking was linked to a range of poor outcomes for children and was not linked to better behaviour.
