Many organizations in the developed world campaign for free or subsidized childcare for all. Others campaign for tax breaks or allowances to provide parents a non-finance driven choice. Many of the free or subsidized childcare programs in the United States are also Child Development programs, or afterschool programs which hire certified teachers to teach the children while they are in their care. There are often local industry associations that lobby governments on childcare policy, promote the industry to the public or help parents choose the right daycare provider.
More specifically, further research indicates that children being cared for by siblings or similarly-aged children (a trend more commonly seen in agriculturally-based cultural communities) have certain psychological and developmental effects on those being cared for. These effects include but are not limited to: mother-child attachment, emergence of childhood developmental stages, formation of playgroups, development of social responsibility, sex differences, personality differences, cognition, and motivation and performance in the classroom. https://youtu.be/eeCahRCgOfI
