American grandparents are surely like any other grandparents. Millions of them love to play with their grandchildren. They buy them gifts. They read to them and prepare special foods. They take them to places. They teach them skills for later in life. And, in many cases,they try to make sure the children learn family traditions.
    Some grandparents are wealthy enough to pay for travel to faraway places with their grandchildren. But others are happy to take their grandchildren to local parks. Or they might watch them perform in some event at school. That is, if they live close enough to attend.
    Today, many Americans live far from their grandparents. School mental health specialist Suzy Karpel says she regrets this fact of modern life. She says she often sees situations in which families need the advice and support of grandparents. Karpel says this is true especially when problems develop. This is when parents might wish most that they had a helpful grandparent nearby.
    If you ask grandparents how it feels to be a grandparent, most will immediately say "wonderful. " They like spending time with their grandchildren. But many will also go on to say that they like being able to return the children to their parents when the time comes.
    These grandparents have already gone through the daily cares and worries of raising children. Now it is time for them to take pleasure in their grandchildren.
