R.D.
I am very old school!! 13 is too young emotionally and they don't know how to handle these emotions!! It is sad that girls this age sometimes feel they have to be identified as having a boyfriend for their identity. This is a big social issue for me!! My 18 y.o. DD was not allowed to "date" until she was 16. This was because they can't drive until age 16. Prior to that, she could go anywhere with "friends" in groups of 4 or up to 20. They could text, talk, etc but she knew she could not "date". They could go to the show and sit by each other with other friends, etc. Way less drama and I think it gave her more of a chance to get to know the boys as people!
Just had this same discussion with some mom friends-1 agreed with me, 1 did not. But just my opinion. If they start dating 2 early, they tend to get closer physically at an earlier age which avoids another whole set of issues.
