Yes I know what you mean and regarding the consequences - I honestly believe the last thing S needs at the moment is to meet OM - his relationship with my W is already severly fractured.
I have just emailed her actually:
"W, S mentioned a few times recently that he doesn't get too see you much etc. I understand it's difficult with your work but do you think we'd be best served to have a look at the arrangements?
Perhaps you could change the 2 days you work, or have S on different days? It seems a shame (for him) that 2 of the weekdays you have him - you are at work so don't see him until late (if at all).
Please let me know what you think.
Thank you - have a nice day."
