um, perhaps I am misunderstanding something here, but didnt you say you had cut of contact with them? Why are you accepting gifts from them then? Why are you allowing them contact with your son? I am not sure I fully understand.
If you are ok with them having contact with your son, then they should understand that he is too young to write a thank you. I disagree that it is your responsibility to take that task over for your son (it sounds like you are treating him as an independent person, rather than a part of your family unit by allowing him contact with these pople, so then he needs to respond as an independent unit). I dont mean any of this harshly- just matter of factly. (I also think if you have broken contact with them, you should also break contact with them for your son. But I dont know the whole situation).
My vote is dont send the thank you.
No, you're not misunderstanding at all. We (Me, Dh and son) have not had ANY contact with them in a couple of years. They never cared about my son or really sent him anything until we broke off contact with them. Now I think they send stuff to make a point (maybe to guilt me for not bringing son around to see them?)
The first year of our falling out I had already bought them Chrismtas presents, so I mailed them. They in return mailed son something. I sent a basic thank you.
The second year I was so disgusted with them and their antics, that I didn't send them a thank you when they sent son a gift card. However, I sent Dh's sister (who lives with them due to her cerebral palsey) a thank you. She had sent a separate gift.
Here we are, another year gone by. Haven't talked to them, don't care to. If I send the card back, I'm opening a can of worms. If I keep it, I'm opening a can of worms. No matter what I do, it's a lose lose situation. Now we don't care, as we don't socialize with DH's family anymore. But I figure if they want to send son a gift card for a toy, fine. But what I was wondering was if I should ignore it like I did last year or be polite and send a thank you.
I see the board here is kind of mixed, lol. I think I may just ignore it like I did last year, as we have had NO contact with them in awhile. None. But we do stay in contact with DH's sister who lives with them, which makes things kind of sticky, as the gift card this year was from her, too. *sigh* I guess my situation is a bit complicated. I may have to stew on this for awhile.
