My kids are very different.
One has a BFF that's his tride and true. Attached at the hip best buddies. A few bumps now and then but over all a long standing good relationship.
The other one has a new BFF every couple of weeks. He talks about his pal, draws pictures and writes their names over their little figures, etc. When I ask what happened to the old BFF (when he starts talking about a new one) he says: "We're taking a break." When I whose decision it was he always says it was his and not the friend's. I don't think it's a drama or fighting issue because he tells stories about what happens at school all the time and I think I'd be hearing about drama from either him or his teacher. Also... he's not my dramatic kid - the other one is.
My curiosity is if there is a "norm" when it comes to friendships in the pre-K or K age.
Thoughts or feedback?
FWIW - at school everyone is described as "friend" and we don't actually use the words "Best friend" - just using it here for clarification.
