We just found out that an acquaintance of ours has lost their three-month-old baby to SIDS. We know both the parents of the baby as well as the grandfather who all live in the same house.
Due to some unrelated family tensions, we will not be attending the wake/funeral. I do, however, want to acknowledge their loss. Should we send one card to all or should we send separate cards to the baby’s parents and to the grandfather?
Ugh. What a tragedy. 
I would send two (one to grandfather and one to parents) just because the grandfather will probably not get as much condolence and yet he has also experienced a great loss. Don’t worry about a long personal note as there’s really nothing you can say, but the fact you sent something is important. Sorry to hear of the loss.
Don’t send a card, though, please. Send a real letter.
Or, compromise: use a blank card (with appropriate picture or front) and write a short note inside. I would also send 2 cards as well.
OK, sounds like a plan.
I’ll try to find a couple of blank inside cards and try to express myself in a coherent manner.
Ugh.
Thanks everyone~
What they all said. I have a new baby and this made me cry. How terrible.
I agree with the others; two would be best. That way you can customize your message. A message to grieving parents is slightly different than a message to grieving grandparents.
Wow, those were the hardest cards I’ve ever written. There are no words to express our sorrow to them. The funeral is over so now comes the hard part for them.
