My girl turned 13 a few days ago... I will admit that this birthday got me.
We are opting to not refer to her as a teenager-- we prefer to refer to her as a young lady or young woman. We are going to VERY slowly work into a few more privileges but I do mean slowly.
I don't really think privileges need to come with age as much as they need to come with maturity and timing, but we are working on things and teaching and training.
