New territory here so not sure what the norm is. DS (15) has a girlfriend & wants to buy her a present. He's got loads of money saved so had offered to pay for it himself. But I usually give him a tenner to put in a card for his mates' birthdays so I was going to give him the same to buy her a present.
How do other people deal with this? Do your teens buy boy/girlfriend presents themselves or do you pay for them?
