<p>mstee, it is a bit odd, I agree. It could have been a mistake or oversight. Then again, you say that they stop giving birthday gifts at age 18, and so maybe they have a cut off for Christmas gifts too but haven’t made it known. I would go by the assumption that it is an oversight (a legitimate assumption to present) and mention that the kids were opening the cards and were delighted to receive the money and you wanted to inform them that Son #1’s card was missing the check and you thought they might want to know, as you assume it was a mistake. They can either confirm it was an oversight or else they’ll inform you it was intentional. You could be polite and say, obviously do as you wish, but is there a reason so that your son may know it? HOPEFULLY, the reason is some arbitrary cut off age (at least that is concrete) and if that is a reason they give, then you’ll know what the cut off age is and simply say it is good to be informed so it is understood by all the grandchildren. Did they give your son a check last year, I assume? I don’t know that you need to get into how you feel, but if you approach it this way, it can be inferred that your son was left out and without knowing the reason, could have imagined many reasons and if it is just an age cut off, it is better to have been told that. I do agree with you, however, that it just is not nice to give to some grandkids and not others. But perhaps they feel the gifts are for kids and not adults, dunno. Some people are quirky in this regard. Basically, when it comes to gift giving, they can do what they want. If there is an age cut off and they wish to inform you, they do. I wouldn’t question or tell them what to do (even though I would not choose what they are choosing to do).</p>
<p>This reminds me recently of something my in-laws said. Let me preface this by saying my in-laws are extremely generous to my children and we are very appreciative of that. They give even when it is not an occasion. My kids have benefited greatly (likewise from my own parents). So, in no way am I complaining about what they give or don’t give as they give the children lots and my kids are lucky in this way for the opportunities. Anyway, we don’t celebrate XMas. We have Hanukah which is nothing like XMas. There is not a lot of gift giving at all. We only give gifts to children. We give to our own kids and to nieces/nephews. I don’t get anything from anyone. The grandparents on both sides also give to the grandkids. The gift giving is entirely for children/offspring.</p>
<p>Back in November, we stopped at my in-laws enroute to seeing our D in a show in NYC. They also traveled to the show (as did my other D from her college). My mother-in-law announced to us, “We’re not giving the kids Hanukah gifts this year. They are adults now. And you (meaning hubby and I) don’t give us anything for Hanukah but our other children do (hubby’s brother and sister).” Well, first, about being adults, it is funny how all of a sudden that came up. Older D is now 21, but younger one is 19, but older D got Hanukah gifts every year until now. I don’t really buy the “adult” reason as they give them lots and lots, same with birthdays. As far as giving them gifts, we never ever have given them Hanukah gifts (though give them birthday gifts, Mother’s Day and Father’s Day gifts, etc.) and have never given anyone (including my parents) Hanukah gifts before. We have always only given to children. This is nothing new and is the tradition I have known of my entire life and I also have been married to their son for 30 years and never given them a Hanukah gift. No different than what is done for my parents. My kids don’t give me gifts for Hanukah either. Their other two adult children are in a different situation. One is not married and has no children. The other is divorced and unfortunately is cut off from contact with his children. So, they have no children to give to and so I guess they give to their parents on this children’s gift giving holiday. I give to my kids and all the nieces and nephews. Now, I thought this was all kind of odd and I was wondering what to say to the kids as they have always gotten Hanukah gifts/money from all grandparents and aunts/uncles. My feeling was that their grandparents have been very generous as of late and so while it would be understandable to not get very much for this holiday, it seemed like making some “point” and would have been better to just give something very minor than nothing at all as I know the kids would truly notice, but that is the in-laws decision. So…several weeks later when the kids were home, my older D tells me that when they saw the grandparents at the show in NYC (that very same day I am referring to that they told us this), the grandparents gave each of them a bunch of money (but didn’t call it “Hanukah”). Younger one never mentioned it to me. Older one says grandparents told her to not tell Mom and Dad. Huh? So, they gave them the Hanukah loot, didn’t call it Hanukah, went out of their way to tell us they weren’t giving them any, and then told at least one of the kids to keep quiet about it! So, what I gather is on top of their quirkiness about gift giving over the years, they were making some point about our not giving them Hanukah gifts (though we never ever have before and only give to children)? I share this because you know, your in-laws may have their quirks too. 
Here is a funny version similar to your story in that last year our girls were here for just one night of Hanukah. It is a pretty minor holiday and we give them a big gift but it is decided in advance with them usually and so there is nothing to open. Usually something they need or want is plugged into being their Hanukah gift that year. But they do get the Hanukah ‘gelt’ from grandparents and aunts/uncles and so that one night, we lit the candles and handed them all the cards that had come in the mail and they both opened them simultaneously. So, when both were opening the cards from one of my brothers, one had a check fall out and one didn’t. We all broke into hysterical laughter making jokes about how they must not like the one D! We all just knew it was a mistake. I did email my brother and told him and he was so sorry. He said he was filling out all the checks and cards for all nieces and nephews on both sides and must have missed the one for one of my kids and of course it was a mistake. So, even though I can’t tell for sure with your in-laws, it is a valid assumption of a mistake and approach it with them like you are assuming it really is one. :)</p>
