Try and get your children involved in activities outside of school. Children that have a lot of unstructured time on their hands are prime recruitment material for gangs. Look to your extended family for assistance. Grandparents, uncles, aunts (yours and your child's) older cousins, all of these can help provide structured time for your child. Remember though, the extended family's activities can never replace the valuable time that you spend with your child.
The single parent who does not have an extended family can try and obtain help from co-workers, parishioners, neighbors, and local organizations such as Big Brothers/Big Sisters, Scouting, gang outreach centers, Y.M.C.A.'s and Y.W.C.A's, Park District programs, youth centers, and so forth. Get on the phone or visit these places with your child as soon as possible.
