I feel like this is a problem the non-profits should tackle. The mother in the article does this, it seems she really is trying to work and not depend on charity/welfare. However, there is some financial literacy / access to capital / cashflow planning type issue going on that prevents her from planning properly (buying in bulk ahead of time). If the non-profit simply offered her affordable diapers (I imagine removing the retail markup alone saves a huge amount), a line of credit or something and helped her plan her diaper supply needs it seems like it could be a helpful service (maybe they do that, article only made it sound like they give away diapers to the poor)
