Two things to note about information concerning Grandparents Rights,
1) As many things in today’s world the laws and information in this area are changing all the time. Look at the dates of the articles, books, etc.
2) Consider the credibility of the internet sites you are searching. The most credible one is by far the AARP site.
I applaud the fact that you are fighting for the best interest of your Grandchildren. Thanks for being a Caring Grandparent.
