Does she
sleep at all during the day now as
at 4 year old she probably doesnt need to, also what time does she go to bed, There could be some insecure feelings there from the Move , if she goes to school how is she doing there is she okay during the day and seems happy enuogh, Make sure she has plenty to do and is not bored and left to her own devises, lots of outside activities, Jump rope, ball games, dancing and Fun.
