Just read your update, so reposting
Please if you can for your youngers do more family times, create memories. Be happy at home. Allow only uplifting things to be in your home, including TV. If your watching something that invites the spirit or satan in your home. My dad, love the man, good LDS man, but cannot get rid of the Sci Fi addiction. He spends a lot of time on the computer instead of with the grandkids and us when we visit. We finally got rid of the tv, missed it at first but glad it's gone. Other things will occupy your time, take you away from your kids.
I think the most important thing you can do is make memories with them. Make sure to laugh a lot and notice the small things. The video games are going to tear them away. They are a waste of time and don't involve family in it.
