Here’s another take that you might not be aware of, or may not want to admit, or can’t see it yourself. One of my cousin’s grandkids is polite, calm and easygoing. His brother probably has ADD, he is out of control, gets into everything, breaks things and has to be watched like a hawk so he doesn’t hurt himself or any of his little cousins. Both kids have hearts of gold, but the rowdy kid takes a Herculean effort to deal with, it is mentally and physically draining to be around him for any extended period of time, even though he’s a sweet little kid. We’ve invited the calm cousin to visit overnight with my nephew, but we told my cousin that we didn’t think we could handle the other child, which is absolutely true. She laughed and said she understood, and mentioned that the other boy is “quite a handful.” Fortunately for us, she and the boy’s parents realize that one of their kids is a lot more difficult to take care of and aren’t upset that he doesn’t get to go on the sleepovers at our house. When we have big family parties, all of us are there together, so it’s a little bit easier to have a whole bunch of adults (as well as little kids) watching out for the rambunctious child, and because it’s a party, no one really expects any of the kids to be quiet. But I could not imagine taking an overly active child on a vacation.
I don’t know you or your kids, but maybe the Grandma thinks your kids are more difficult to handle (for any number of reasons).
I know quite a few parents (not the parents of my active cousin) who don’t think that their kids are difficult at all, even though everyone else has a difficult or unpleasant time being around them. Parents are often blind to the mis-behavior of their little tykes too. Just go into any grocery store or Walmart where some child is having a meltdown and the parents take no notice.
I’m also curious to know if your kids, or you SIL’s kids are girls or boys. Grandma might favor girls, when it comes to trips, because they tend to like the same kinds of things that Grandma might like, such as shopping, getting their nails done, going to tea, where as boys might prefer things that Grandma doesn’t care for such as going to a ball game, or going swimming at the beach, or going to a video arcade.
You say you have spoken to Grandma, but I’m not clear on what answer she gave you, or what exact question or concerns you gave to her. Your husband should be the one doing the asking, too, because if YOU ask her, it makes you look greedy and un-gracious. He should ask his mother, “Hey mom, I noticed that you took Jen’s kids to Disneyland and Chicago and San Francisco. I really think Bob and Mark (or Kayley and Vickie) would enjoy going with you on some of these trips. Would that be OK? I don’t want you to be put out by the expense, we would pay for them to go. I also wouldn’t want you to be burdened by having to watch out for 4 kids instead of just 2. Would you mind if we went along too, or is the idea of all of us going at once just too much? I was just wondering, because Bob and Mark would really enjoy spending more time with you too.”
I’d like to know the answer to that conversation.
I don’t think you should be mad, until you know the reason for why she isn’t including your kids on the vacations. It might not be what you think at all.
