The DC get birthday card+cheque and then a cheque at Christmas from DH's dad every year. All great and much appreciated etc, except he always says how difficult it is to remember all of his grandchildren's birthdays etc (he does have 7, 3 our our DC) and it's become a bit of a regular complaint. Which I get because he's only started doing it since DH's mum died 3 years ago and he thought it was her job. But now the kids are getting older I don't want them to hear him complaining about having to remember their birthdays etc and how difficult it all is when they get their card. My eldest is really sensitive to things like that. I feel like saying either give the card or don't, either is fine, but don't say anything on their birthday.
Do you think I'm being overly sensitive?
