Hi I have 2 children aged 7.9 and 3.9. There is a girl aged 14 who is a very good family friend, very sensible and comes up to our house several times a week as she lives few doors down. Kids adore her, she's does them too. She has been coming up since she was 9. I was going to leave her with kids 5-8 tonight whilst me and my husband go out for a meal approx ten mins away. I feel completely confident to do so. My mother however been on phone saying she's too young. I've looked on the Internet and some sites say 14 some say 16. I'm unsure now :( she's a lovely girl but I want to be sure I'm doing the right thing. Opinions please ladies.
