I tend to lean in this direction too. If things get nasty between H and OW, where does that leave child. H doesn't want to see anything that reminds him of mistake, OW doesn't want anything that reminds her of H, especially if it has no pull in the sitch. A child does not deserve that. At least give the child a clean start and not a position of possible dispise. But with that said I don't know if you will have much say in the issue. I would get your thoughts in order, in case H has some input to the sitch.
