- ECD in emergencies involves providing early childhood development services during humanitarian crises caused by natural disasters, conflicts, or a combination. - Emergencies can weaken children's protective environments and layers of support, exposing them to toxic stress that impacts brain development and increases the likelihood of long-term negative outcomes. - Mobile ECD services delivered by local community teams in Nepal following an earthquake showed promise, with weekly visits providing early learning, parenting support, health/nutrition, and referrals without needing permanent buildings.
