    Bedtime by age — your questions answered

    What time should my child go to bed?
    🔬 Why sleep matters for children
    🧠 Brain development

    Deep sleep is when the brain consolidates memories and strengthens neural connections formed during the day. Children who get adequate sleep show measurably better learning, attention, and memory retention.

    📏 Physical growth

    Growth hormone is released primarily during deep sleep. Children who consistently under-sleep show measurable differences in height and weight gain compared to well-rested peers.

    😊 Emotional regulation

    Sleep deprivation in children manifests primarily as behavioral problems — tantrums, aggression, difficulty focusing, and hyperactivity (often misread as too much energy when it's actually too little sleep).

    🛡️ Immune function

    Cytokines — proteins that fight infection and inflammation — are produced primarily during sleep. Children who get adequate sleep get sick less often and recover faster when they do.
