Pretty sure my DD has ADHD, at school presents well, can focus on work, however will request a LOT of toilet trips, always be the first to ask to help give out books, so uses these as an excuse to get up and move around.
Unfortunately I've had the non sleeper and destructive traits from her, more so when little, she's still a crap sleeper, but she at around 9 took a pair of scissors to her bedding, used to steal stuff, steal items in the house to make go awful slime concoction in her room, would draw up her walls, pick the plaster off her walls, just a few examples. She's very impulsive so doesn't think thing's through.
Taps her feet or drums her fingers continuously, interrupts conversations, says thing's and you think why on earth would you say that. Loses everything and is massively disorganized.But she's kind, funny, a high achiever and not at all a bad kid.
