It's not alway easy to do but asking for help can be a big stress reliever. If you have other children with extracurricular activities, make arrangements with other parents to share transportation responsibilities. For example, you agree to take Jimmy to and from football practice one week, and Jimmy's parents agree to do the same for your child the following week. This may help free up some of your time while helping another parent as well. In return you might feed their cat while they're away or just bring them a plate of homemade cookies.
Most people are happy to help.
