Hi I'm kiara and I hope this is helpful . I'm a fifth grader and I'm 11. There are people in my grade dating. Alot are 10 and 11 year old. And I'm not saying having a crush is bad. I have a friend named corina and she has done somethings not even 70 year old havent done. And i would say mybe 9th grade and 15 year old. So please take my advice and watch out who your daughter is hanging out with because sometimes they ask and do things under pressure. Have a nice day or evening bye
