How is your son doing now? I have heard that passing kidney stones is some of the most excruciating pain one can experience. Poor little guy.

When the kids are with your W, dont they call you each day? Maybe you can arrange something with your W so that you can call to talk with the kids each day. My W has the kids use her cell phone to call me daily and when they are with me I let them call her at least once a day. They really like dialing the phone.

I dont think it is a good idea to point out to your W that she is being neglectful as a mother. She will always try to defend herself.
