I posted bout this when it happened. Not sure if I deleted it since.

But. We give BM a calendar of our days a year in advance because DH's work schedule is a predictable rotation.
Mind you that is a favor we for BM but it also makes things easier for us too.
Technically we are just supposed to let her know our days 30 days in advance.

Well DH's schedule changed this year. (5 months ago) so the rotation he's had for the last 6 years for SD had to be changed. Bratty BM who doesn't work at all hitched a fit about it. But of course she had to get over it in the end.

WELL NOW DH is being moved to a different location and his rotation so going to change again. (It's actually going to go back to the old rotation). This means we have to let BM know its changing back.
Luckily the school year is almost over so we won't have to deal with this much longer. And the next fresh calendar will be created (by yours truly) at the end of summer.

I just don't know how she is going to react. We created the new calendar to start 30 days in advance per CO's rules to "changes". So it's not like we made her change plans or anything last minute. (Like she even had plans. (Eye roll))

So we would do the same again. Just work out this current schedule for 30 days and then start the new (old) one.

Ugh. Not in the mood to deal with her shit
