Huffington Post's CARING FOR ELDERLY PARENTS is a series of articles and links that come in handy. http://www.huffingtonpost.com/news/caring-for-elderly-parents/
AARP is a great resource for older people but also for those who care for them. Here is one article: http://www.aarp.org/home-family/caregiving/info-09-2013/my-life-as-a-caregiver.html
Of course WebMD is a reliable source. It is also great when your dad refuses to go to the doctor. I don't recommend SELF diagnosing but diagnose away when it comes to stubborn fathers. http://www.webmd.com/healthy-aging/features/role-reversal-caregiving-for-aging-parents
While we are on the health track, you can always count on the MAYO clinic too: http://www.mayoclinic.org/healthy-lifestyle/caregivers/in-depth/aging-parents/art-20044126
Finally, here are some resources from PBS: http://www.pbs.org/wgbh/caringforyourparents/
This is obviously not a comprenhesive list but as time passes, I will continue to share any resources that might be beneficial and I would appreciate you doing the same in return.
Until next time,
Michele
