We don't think it is very hard here to entertain our children. We really don't watch much TV, we don't have a video game system, and we don't have tons of toys. What we do provide is plenty of craft supplies, Lego's, pretend type activities, and outdoor play equipment. We also let the kids have friends over on a regular basis. I think building relationships with friends is more important than providing electronic entertainment. Now, my oldest has a cell phone (my old one) and we did buy her an i-pod touch for her birthday, but we make her put these things up during homework time and we make her put them in the living room at night. We also do the same when friends spend the night. The phones come in the living room at night.
I read somewhere (I think the Tightwad Gazette) that this is called creative deprivation. You let your kids get somewhat bored, and they will entertain themselves or each other. I have found that out to be true. Sometimes I have to hear for a while that we have nothing to do in this house, but then when I tell them that they can do some chores, they quickly find something to do to entertain themselves. Ha Ha!
