"BTW I agree with whoever mentioned it was a way for them to touch base and then go out even more boldly to explore their world independently."
I don't know if that was me, I have certainly written similar.
To the world DD2 is the most confident, mature and socially astute child you could ever wish to meet.
She did a good line in preteen attitude long before she stopped BFing.
But in fact it's a bit of an act, she is the one who worries what people think of her, the one who knows the world isn't nice and safe. Even at 12 with a boyfriend and a whole gang of ~teen friends. It's her who needs a big hug.
Not my quirky, often bullied, socially inept, dyslexic DD1. She was born with an grown up head on her shoulders and a deep self confidence.
Only now as the bullies have began to realise, they will no longer get any response and the teachers see her getting good marks despite her difficulties do the out side world see it.
DD2 always has, she'd never normally admit that big sisters in charge if they or on their own in town, but she did the day they managed to loose DH and me totally.
