My DS is 17 and has a 16 year old girlfriend. They've been together a year. Almost from the beginning he asked if he could sleepover (her bed) at hers. She asked him. I was gobsmacked her mother would allow it (he was16 she was 15). So I said no until he was 17. So he's been staying there regularly for 1 night a week since he turned 17.
He's her first boyfriend.
He wants to spend more than 1 night there now. I am saying no......but I've no idea if I'm being too strict???
