AirParents is a free app that connects parents in the same school or area with similar before and after school child minding requirements. It takes the awkwardness out of asking another parent for help when you are standing in the playground side by side.
Once it's established that you both need help before or after school with your child minding you are able to connect and discuss your requirements and in turn both benefit from the relationship and the network you are able to create within your child's school.
