Miedos nocturnos en preescolares (oscuridad, monstruos, pesadillas)

Los miedos nocturnos son normativos a esta edad y casi siempre remiten; la respuesta del adulto debe validar sin amplificar y mantener rutinas.

Contexto

Entre los 3 y 6 años emergen miedos típicos (oscuridad, monstruos, sombras, ladrones, separación) impulsados por el desarrollo de la imaginación, la teoría de la mente y la dificultad para distinguir realidad/fantasía. Aproximadamente 70% de los preescolares reporta al menos un miedo prominente, pero solo ~5% cumple criterios de trastorno de ansiedad. Las pesadillas ocasionales también son comunes.

Lo que dice la evidencia

  1. [claim-fears-normative]mental-healthEvidencia media

    Specific fears (the dark, monsters, animals, separation) are common in 3-6 year-olds and typically remit with development; clinical concern arises when fears are persistent, impairing or developmentally atypical.

    Los miedos específicos a esta edad son frecuentes y suelen remitir solos.

    Matices: Use DSM-5 thresholds (duration, impairment) to distinguish normative from clinical anxiety.

  2. [claim-family-accommodation-anxiety]mental-healthEvidencia alta

    Parental accommodation of a child's anxiety symptoms is common and is associated with greater symptom severity and impairment.

    La acomodación parental excesiva (dormir con el niño cada noche, revisar el clóset 10 veces) mantiene y amplifica el miedo.

    Matices: Most evidence is cross-sectional; mechanisms are still being clarified.

  3. [claim-bedtime-routine]sleepEvidencia alta

    Consistent bedtime routines and behavioral interventions (graduated extinction, bedtime fading) are effective and safe for resolving toddler bedtime resistance and night wakings; they do not harm attachment or stress physiology in RCTs to 12-month follow-up.

    Rutinas predecibles a la hora de dormir reducen resistencia y despertares.

    Matices: Some attachment-oriented critics argue against extinction methods; RCT evidence does not support harm but follow-ups remain limited in length.
