For those a little more experienced with a teen, is it normal for girls to change friends often? My dd13 has a few constants who she has been friends with since starting high school, but other than that, she changes her "bff" fairly regularly - she'll hang around with someone for a while (a few weeks - to a couple of months), they will be joined at the hip, then it's over. Onto the next one. I also find that girls are incredibly bitchy - they form "friend groups" who are against other "friend groups"... I always tell my dd to be kind, that you don't know what someone else is going through and not to be nasty, but there's always bitching going on in one group chat or another, fall outs happening and general nastiness (not from dd but in general in her year) - again, maybe normal?, but some kids are just horrible!
