I’m amazed by these replies. Surely whether it’s rude is entirely dependent on family dynamics.
In my family, the norm is that visitors are provided for. If it was Christmas, I’d take my parents presents, and I guess other times I might take a token gift, but there would be no offence taken if I didn’t. They’re simply glad to see me. When they come here, I wouldn’t expect them to bring me anything either. I consider my home theirs and theirs mine, up to a point.
It was the same when I was a child and we visited grandparents. They didn’t expect anything to be brought. Presumably if money is short, then tactful help is in order, but otherwise not necessary. It’s family and one of the best things about family is surely that they don’t take offence at unimportant things?
In addition, your daughter and son-in-law were caring for three children, the youngest of whom is pretty much still a toddler. I bet they arrived and were wholeheartedly grateful for a rest. I know when my children were that age, it was a massive treat for someone else to make the dinner.
Now I would help out much more in the kitchen, as would my young adult children.
When you were young and you went to the in-laws, were they struggling that you felt the need to take the turkey? I think if people are struggling for money, it’s a different matter.
OP, you say you were perfectly happy and enjoyed their company. Why spoil the memory for yourself now? You’re setting yourself up for future resentment unless you plan to embarrass your daughter by telling her off for “being rude”.
