Yes, do what makes you happy June!
FWIW, my advice is to go for it. For one, even if you cook a big meal, you won't have to cook for a week afterwards with just the left overs and then you can make yummy soup with the rest of the meat. when i bought my turkey last week, there were some quite small ones. You don't have to cook a 20 lb turkey. They had some as small as 9 pounds. For my family of four, a 12 lb turkey is perfect.
And more importantly I agree with pkessler. It is important to establish your own traditions. I have always done a Thanksgiving dinner - in the States we had ours in October when it's Canadian Thanksgiving and here, I just had it (can't always get Turkeys here for the first mon of October!) We have special things that we only have for Thanksgiving which differentiates that meal from our typical sunday roast.
My kids depend on those special meals, they insist on them and really look forward to them. This is your family and you need to have your very own traditions. And who knows, maybe you'll be starting something really great amongst your own extended friends and family community!
