Spring Break Parenting Time

My husband just requested a week of the kids' spring break parenting time - giving them more than four months notice.  Odds are that she'll come back with it already scheduled up the wazoo for the kids and tell him no. 

If she does that, I hope he demands his xmas parenting time.  That will include xmas and my stepdaughter's 18th birthday (which the ex is not going to want to miss).  He's given xmas to the ex the last several years because the kids don't want to leave her alone at xmas (whose fault is it that she is alone after all these years?  HERS!) and his employer has him working through some of it (most parents do) but there has to be one chunk of time he has with his kids this school year!
