Hi, I do agree with some of the answers here as I am a mother to a 10yo girl ( who even when she is yawning and yes will still complain that I'm mean cause I am sending her to bed too early in her eyes, I would take your daughter to the doctors first to rule out any medical problems...... then on to changing her habits, like someone else answered don't let your daughter sleep after school and maybe reward her when she goes to bed at a resonable time. Good luck and I hope it works out for you and your daughter.  

I think it is really odd that your 10yr Old is actually sleeping so much. Is he/she having any problems at school or at home which may be them not want to face the world and go to sleep to not deal with their feelings. I would probably talk to your child about this. I have been through depression and slept all day long and still felt tired. If I am way out here maybe you should trying and keep your child active after school so he/she doesnt go to sleep till later, say 8:30pm and you will notice that he/she will wake up more refreshed from having a less disturbed sleep

sorry you could also try shortening this nap by 15 mins each day until she is not having it at all this should help make the transition a little easier

I suggest not letting her sleep in the afternoon if she is very tired i would take her to the gp.

You may find she is falling asleep from boredom or simply because she has an unusuall sleeping pattern

Hi there falling asleep after school is so not normal for a 10yr old, infact not being able to fall asleep is the norm. At this age she should be full of vigour and complaining that you are sending her to bed too early.

If I were in your shoes I would be making an appointment with the GP to dicuss this as soon as possible, as others have said it could be an Iron deficiancey or as she is heading into menstrual age she may have hormonal or thyroid issues.

Please take her and get a check up, if nothing else it will rule out health issues, then you can start getting her into a proper routine.

Your daugter could be low in iron I would take her to the doctor and get some blood tests done just for peace of mind.

my advice to you would be to keep her active after school either doing her homework or taking her for a walk or to the park or even to visit a friend she probably won't sleep there.  try and change your routine after school then give her her tea then bath read her a story then let her sleep.  if she really is still tired after a couple of weeks of trying this i would take her to the doctors and just get her checked over to make sure there is nothing else.....but i should imagine keeping her active after school will change her sleeping pattern for you and allow you a bit of you time too!  hope all goes well!

I don't have experience with children your daughters age (yet), but I don't think it is normal for her to sleep after school and be awake half the night.

You need to stop this habit now or it will be one she will keep for life.  Maybe get her to do some chores instead of sleeping might help, or homework.  We won't even let our 2 year old sleep in the afternoons because she is up half the night when she does.
