I have a 3 1/2 year old son who has great problems with sleep. He either does not go to sleep at bedtime (this is solved to some extent now by giving him exercises in the evening thus making him tired) or gets up early morning (generally around 4 or 4.30 am). He's unable to sleep again after he gets up at that time. He gradually becomes fresh and stays awake for about 3 or 4 hours after which he starts crying as he is very tired and sleepy.
I've been giving him Nuxvomica 200 at about 2 am for the past 1 month and it seemed to work (though he used to wake up at the same time, he would soon fall asleep). But now he seems to have developed a resistance to it and it does not seem to work any more and he still wakes up at that time.
I tried Passiflora and Avanesativa but they have had no effect.
Anybody has any suggestions as to what I can do to help him sleep through the night? Any medication that will have effect for a long time? Homeopaths please, any suggestions? Any parents out there faced similar problems like this?
Please help!
