I have a 9 yr old dd. is this just one of those natural twists that people joke about teenagers having?
or could something be wrong
diet and energy levels good. she eats the sake as we all do akd dd2 does and she's fine. up and happy every morning. gets a bit tired after school but she's In reception and to be expected etc
dd2 however hates getting out of bed. always whining she's to tired. she moans we never do anything (not true) but when I arrange a trip out she is a struggle to get out of bed and is actually very stroppy as she's apparently tired 
they do two activities a week, plus school, plus the usual going out to play on scooters/bikes etc.
happy to run about and play with a neighbours dog....
just no matter whether she gets up at 6.30 (school day) or gets to sleep til 9/10 in the hols and Sundays she still says she's tired and can't be bothered to get dressed etc.
if we go out she seems fine. happy to run around and play.. I ban the screens on a school days so they are encouraged to play or go out to play.
she does always look tired but she's also pale skinned so would anyway.....
teachers haven't ever said anything she's fine in school so not sure if she's putting ot on or whether I should be concerned. .
