I say that if the request was made for no gifts, you have to abide by it. For whatever reason, the parents don't want gifts, and bringing one if no one else does will make things awkward for all, especially the birthday child. I have heard a lot lately about families making the no-gift request. That being said, I also feel it IS the child's birthday and that is special and should be celebrated!! What about bringing the birthday boy/girl a balloon? Or at least a nice card with maybe a picture drawn by your son? Even a little "book" that your son writes about his friend, and illustrates (craft stores sell blank books that you could write in while your son dictates the story, then he can color the pictures). It at least acknowledges that his friend is turning 3, but it's not a wrapped toy or traditional gift. You might also bring a snack to add to the festivities. Good luck and let us know how it turns out. My oldest is turning 3 and I'm wondering if this might happen to us in the future!
