A Capitol Hill babysitting co-op is a group of parents in a neighbourhood who form a club to help each other with childcare. The way it works is that each parent takes turns watching each other's children one night a week for free. That way, parents can still maintain their jobs and have time to do the things they love without needing to hire a babysitter. It's a great way for parents on a budget to get help with childcare and to get to know their neighbours!
