Well, I guess all kids are different. I have 2 sets of twins and while we would never dream of trying to tell a guest what to bring, we do try to drill into the heads of my family that they MUST give identical or at least very similar gifts. I don't care what the gift is, I just need it to be the same, so that we don't have all out war and/or one unhappy crying child at bedtime because the other child has the "best" one. If grandma gives my twins two stuffed animals, it never fails that one wants what the other has, and the other wants what she has...So I would recommend buying two gifts, not one, and buy something less expensive so that you can buy two. I like the idea of calling the parent for ideas; I always do that for any child I buy for. But fyi one of the favorite gift items that my children give or receive is the Crayola magic markers and/or paints that only color on specially treated paper along with the special paper. they have it in Diego coloring books. It's great for trips and entertaining the kids and litle supervision is needed.
