Should my daughter write thank you cards for this?

How old is she,, I would say under 7 she could phone them, over that, I think it is a very nice practice to begin!

I wouldn't. They are grandparents. Too close for a formal thank you note in my opinion. Don't they get her gifts all the time? She could, it wouldn't be wrong, but I think if you are very close it is unnecessary.

yes. it is a wonderful habit to instill in her. they can be simple and homemade.

I think they would love a little andwritten note!!! Nothing fancy, just somethng she made. They'd probably put it on the fridge and it would bring tons of smiles!!!

Yes. I use to make them on the computer for my daughter using Publisher with pictures from the event. She would tell me what to say I would type it out and she would sign her name. I found out recently that her grandparents have kept every single one. Making them on the computer is a fast way -when they are so young it is hard on them to write so many notes - this is faster and you can get them in the mail within the required time frame.

I like pp^ idea.

Absolutely

Maybe take a picture of your dd with the item received, and add a caption to it saying "Thanks again!" And email it to them if they have email?
