It was my Dads birthday over the weekend and I sent a card with "Dad" on it from me, DP and dsd but afterwards I wondered if I should be putting dsd on our card or if I ought to buy a separate one. I don't think it would have been appropriate for her to send a "Grandad" card because he isn't her grandad but I could have bought a separate, ordinary birthday card and got her to write it for him, which I know she's be more than happy to do
What does everyone else do?
