MIL's Fiance (let's call him F) has just been given another grandchild but the poor baby is in a bad way. He was transfered yesterday to a specialist hospital and has had surgery today. I know tF well - my DCs don't call him Grandad but he's as good as. I've met his daughter and her husband once or twice.
Can i send them a card saying that we are thinking of them and wish the baby a speedy recovery etc? And can I send a card to F too? And if so, should i address it just to F or to F and MIL?
TIA
