I keep cell phone bills that log all the calls. I'm going to be going through those next...that will show the times the kids have called him as I don't have long distance on home phone so when they call him it has to be via cell phone. He almost never called my cell phone before this as the kids answer the home phone so it will show that too. I only got caller id on home phone recently due to our move...it's hooked up through my cable so when I'm watching tv and phone is unplugged I do see who is calling but it doesn't register on phone id. The letter should be an interesting read...wonder if he sending it certified for proof? Regardless I have decided that when it comes time to mediate that I will also be asking that he pay a higher portion of the transportation costs on top of asking for the visits to be supervised. I know it's going to end up in front of a judge so I may as well ask for everything.
