so, so familiar. we realized this year that DD5 truly believes her true peers are adults. this is pretty great on a number of fronts (great conversations, excellent judgment, unbelievable maturity.)
but... the flip side is that it's flat-out exhausting - and she has no natural concept of parental leadership, so there's always lots of work to be done there! i have no idea how you guys with more than one of these survive. i never say this when people ask - but that's the real reason we stopped at one!
