DD is 12 and hasn't seen her dad since she was 6. His choice - he has a new wife who has made it clear she doesn't want him to have any involvement with dd. He doesn't pay maintenance.
For the last few years he's started sending her present at Christmas and birthday.
It usually upsets her as it reminds her of her dad.
His Christmas present has just arrived. I'm considering intercepting the presents and not giving them to her to avoid upset - AIBU?
