Here are some suggestions:
-- Find a support group—either a group specifically for grandparents raising grandchildren or some other support group where you can share your challenges with others who will understand.
-- Talk to someone. This could be a friend or relative or a professional, such as a counselor, family doctor, or someone at your church or temple. Unburdening yourself can be a stress reliever.
-- Take a break. A short time away from your grandchildren may give you some time to relax. Look for a trusted adult who can babysit or take over while you're out.
-- Take a parenting class. A class may help you to feel more comfortable with your status as a caregiver for young children. It will also provide resources in the form of your teacher and the other students in the class.
-- Learn to say "no." You don't have time to do everything. Learn to make priorities, and eliminate the unnecessary tasks in your life.
AARP runs a Grandparent Information Center, where you can sign up for their newsletter, check their message board, and search for a local support group.
