Nice one East. One thing though, even if your way works better, do not offer advice, because I'd be willing to bet it is not received as it was intended (to put it bluntly, you are accusing your W that she is a bad mother). Stop that, she will manage. Try to resist the urge in the future.
And do not tell your W about dates and/or no dates. It sends all sorts of weird signals and none of them good...
Other than that thumbs up on your GAL. Take care buddy...
