Gillick needs to be reviewed
This with bells on.
The only time I really hear about Gillick is when people gleefully post that it's not your decision as a parent anyway, because Gillick. About all sorts, not just vaccines.
My very academically intelligent, fairly mature 13 year old tried to dig a piece of toast out of the toaster last week with a (metal) spoon because of course, he knows using a knife is dangerous. Ffs. He just never thought, apparently.
At 13 they're still children that often don't have the capacity to consider anything greater than what to wear. And call me sexist but ime boys definitely more so than girls.
