Hey Surfer. I'm sorry you're going through this. You've come to a great place for help, though. I don't have kids so my case is quite a bit different from yours. Hopefully one of the vets with kiddo experience swing by, but I think the best advice I've seen, and agree to so far, is that you need to get that schedule straightened out ASAP. The sooner you get that done, the sooner you can start to stop worrying so much about WW, and focus on yourself. You don't want to be drug around and doing things based on her schedule alone.
I made the mistake at the beginning to work off my WW's schedule, and it was horrible. I was constantly being made 'available', and that's just not what we need in a time like this.
I don't think calling the kids to get updates on their activities is a bad thing, but I'm not the expert when it comes to kiddo scenarios (again). But you're right, in thinking, that if you do call, you ask immediately for the kids, and then talk to them directly, and there's really no reason for them to even hand the phone back to mom before you hang up. is there?
