DD is 6 and she’s having one friend to stay for her birthday tomorrow .
I’d like them to have fun but I don’t want to send the other child home the next day grouchy and dog tired .
I was planning pizza and a movie around 6.30pm .
What time should I ask for lights out and for quiet ?
Or should I just let them stay up as long as they like ?
I have another DC so I need to think of her getting to sleep too
