My son and his wife are hosting my husband and I for Christmas, as well as my sister and her husband. My nephew will also attend the holiday dinner, but not as an overnight guest.
So far, it seems I've been relegated to "bring muffins and some wine" duty, which is fine. I want to be helpful, but I know they're excited to try their hand at hosting a holiday for the first time. Besides helping to watch the kids, and offering to help with the meals and household chores, what can I do? Any advice from those of you who have either hosted your ILs, or been guests of your DILs?
So the first thing to do is to get your attitude in check. You are clearly miffed at being relegated to bringing muffins and wine. Your post also has an air of superiority from the "they're cited to try their hand at hosting".
Behave like a guest and use guest manners. Good guests engage in sparkly conversation, they offer assistance and listen carefully to what the host says. If the hosts says no I don't need help in the kitchen, please just relax and enjoy yourself then go do that happily. Do not sit on the couch and scowl. Do not go into the kitchen anyway. Do not offer any tips or advice on how the host could do something better.
If you are staying over night, again behave as if you are a guest in someone else's house. This is not your house. Respect that the children have bedtimes. Offer to help clean up. If your host wants or needs help she or he will accept it.
