My mother, too... so appreciated the chance to see her grandbabies!!!
Just the thought of not making a slight adjustment to insure that everyone could make it, and is comfortable... THAT TELLS THE WHOLE STORY.... They obviously do not care about seeing your children AT ALL.
And the person who just posted that some of the others obviously NEVER had a baby who needed a schedule, is SO right. Been there, done that.... I didn't even need a watch or clock... I could TELL TIME by my son... Until you've been there.... don't cast stones.
And, OMG, just the thought of TWO babies not on a schedule.... 24/7 willy-nilly....
IMHO, anybody who is making negative judgments about the OP in this particular situation are just way off base.
And, IMHO anybody who would host a 'family' holiday in this way are 'hostzillas'.
OP, I am sorry that your family are being this way.
If I were invited to 'stay home' that is exactly what I would do.
I have posted earlier that I have definitely been-there-done-that.
I've learned to two things....
1. Don't go out of your way to please those who do not show caring and respect, and are controlling and who will make negative judgements.
2. Always, ALWAYS, put your child(ren) first. You are their mother.... You know them best...
