Decisión sobre colecho (compartir cama con el bebé)

El colecho es un tema con recomendaciones encontradas: la AAP lo desaconseja categóricamente; otras instituciones (UNICEF UK, ABM) proponen reducción de daños para familias que lactan. La evidencia muestra que el riesgo depende fuertemente del contexto.

Contexto

"Colecho" puede significar compartir habitación (recomendado) o compartir cama (controversial). El riesgo de muerte súbita asociado a compartir cama se concentra cuando se combina con tabaquismo, alcohol, sedantes, sofá/sillón, prematurez, bajo peso al nacer o superficies blandas. En ausencia de esos factores y con lactancia materna exclusiva, el riesgo absoluto es bajo, especialmente después de los 3-4 meses, aunque no nulo en los primeros meses. La decisión es personal y debe tomarse informada.

Lo que dice la evidencia

  1. [claim-bedsharing-context-dependent]sleepEvidencia mixta

    Bed-sharing risk for sleep-related infant death is highly context-dependent: it is concentrated when combined with parental smoking, alcohol or drug use, sofa or armchair sleeping, soft bedding, or prematurity. AAP recommends against bed-sharing categorically; UNICEF UK and several researchers favor a harm-reduction approach for breastfeeding dyads without those risk factors.

    Es el claim central: explica por qué el riesgo es contexto-dependiente.

    Matices: Studies are observational; residual confounding is possible. AAP and harm-reduction camps disagree on whether risk in "non-hazardous" bed-sharing is truly null below 4 months.

  2. [claim-supine-sleep-reduces-sids]sleepEvidencia alta

    Placing infants on their back to sleep on a firm flat surface, free of soft bedding, in the parents' room but on a separate sleep surface for at least the first 6 months substantially reduces the risk of sudden unexpected infant death.

    Aporta el marco general de sueño seguro que no cambia, se comparta o no la cama.

    Matices: Risk is concentrated when guidelines are combined with parental smoking, alcohol, sofa-sleeping or unsafe surfaces. Cultural practices around bed-sharing vary widely.

  3. [claim-exclusive-breastfeeding-6mo]feedingEvidencia alta

    Exclusive breastfeeding for the first 6 months and continued breastfeeding alongside complementary foods through 2 years reduces infectious morbidity and mortality, particularly in LMICs, and is associated with modest cognitive benefits.

    El colecho facilita la lactancia nocturna y se asocia a mayor duración.

    Matices: Effects on long-term metabolic, allergic and behavioral outcomes are smaller and partly confounded by socioeconomic and family factors (Colen & Ramey). Maternal mental health, equity and structural support must accompany promotion.

En estos contextos, el colecho en cama está específicamente desaconsejado por todas las guías. Compartir habitación con superficie separada sigue siendo protector y compatible con la lactancia.
