Sponsoring a child through Give Hope 2 Kids involves 3 steps: 1) choosing a child to sponsor from profiles of children in need, 2) signing up to sponsor at $35, $70, or $140 per month, and 3) starting a relationship by exchanging postcards and photos. The document provides profiles of 5 children - Eugenio, José, Jefrey, Carlos, and Daysi - who are in need of sponsors to support their education, healthcare, and basic needs.
