nettie your ds sounds so much like my dd. The age is very similar so I am guessing it is age related? DD wakes her little brother up, or rather used to, she sort of helped get his own bedtime routine to start so early I think. She also does not very much we ask her, falls on deaf ears, or ends with a fight/tantrum.
I guess, this is one of the times when that old mantra is wheeled out 'this too shall pass' so get repeating!
We try to say to DD, go upstairs and play with your toys quietly, or, you can stay downstairs, but there will no tv on, and no toys are allowed down until 7am so you will be bored. It is starting to work, she will want to stay down then, after 10 mins she will go back up, and now sometimes she comes down, we send her back and to play and she goes up without a fuss. not always, and she rarely if ever goes back to sleep, unless it is really really early.
Once, she went back to sleep after waking at 5:30am, and slept til 8am, then woke saying 'oh i slept for a long time, i slept very well' 'how do you feel for your long sleep' 'very good, i feel very good mama' never to be repeated!
