My favorite organization is Community Impact Lab. Lately they have been doing a lot to help refugee women with young children and new babies.
"Community Impact Lab strives to be a force for action and to expand opportunities everyone, especially women and children, have to be impactful. We believe that by engaging families, empowering parents, and working together to tackle challenges in real ways, we can create the sea change necessary for every person to live, give, and grow to their fullest potentials. Our Social Good, Learning, and Family Labs remove barriers to progress by giving opportunities for parents and their children to do social good, build supportive circles, and share knowledge and skills. We leverage grassroots passion and energy with innovative projects and bridge the gap between needs and available resources."
