I was reading the other day about pre teen girls and marshmallow brain phase.
I know it's just one persons view, but there seemed to be a lot of people agreeing.

You know her best. I'm sure you know whether it's just her personality (some kids are fiercely independent, some not so much), or whether things just aren't quite right. Can you pinpoint when things started to get frustrating for you, or has it just been a really slow progression with lack of development? Is she bothered by not being able to do as much as her peers or does she just seem content muddling through.

I hope you can get some sort of help with this for you both.
