Unstructured Time with Children
There is a lot of attention drawn to "unstructured play" time as valuable in a child's development but it is also a very important part of "team-building" and bonding between parent and child. As parents we need time to be open-ended and creative with our kids. Free time where new ideas and mutual interests can be explored can change the direction that families and children pursue. A lot of learning goes on in school and parents need unscheduled time to stay in the loop of where their kids are in their peer groups.
Access to definitive information can be a big part of stimulating and pursuing family interests. The family computer can greatly augment conversation. Wikipedia is a great resource.
