See, to me, the order is abundantly clear. We alternate the weekend schedule 3 times throughout the year, after each of his 3 vacations. So, that is how the schedule changes take place. I started there with my calendar, and alternated the weekends after those 3 vacations. Then I went back, and if his vacation time included any part of a weekend, the next weekend becomes mine, even if it was his scheduled weekend. This does not change the fact that the weekend schedule has swapped. So, on either 1 or 2 of the changes, it so happens that I have the children 2 weekends in a row.
Again, I know why the judge made this ruling. He wanted the weekends totally swapped all together, so the he always had the children on the same weekend as his new family. I did not want the swap to happen, because then I would not have the children on the same weekend as my extended family. His lawyer kept using the argument that I was telling them that my family was more important than his. The judge, to show equality on both sides, made us switch weekends throughout the year, so that the children got to spend time with the extended families on both sides, not just one. It does make the schedule much more complicated, but the reasoning was sound.
As far as your suggestion to alternate who gets that first weekend after his vacation, it won't always work out that I have the children 2 weekends in a row. For instance, after Christmas, the alternated schedule put me with the first weekend. That weekend was mine no matter what because of the judge's order, but it did not affect anything because it was my weekend under the changed weekend schedule. This time, it does affect him, he looses his weekend. Next one, after Summer, it all depends when we have our summer vacations. So, it's not like this provision will always have him missing that first weekend.
Just get a clarification from the judge. That is going to be the only way to resolve this.
