I have a 2 yr. old daughter of late she has been screaming a lot...u don't do a thing that she wants or the way she wants and there is howling and loud howling, also her sleep is not at all sound, she gets up every night within two hours of sleeping and every morning when she gets up she has to cry, also she does not play with any children even though we take her to the park in a routine but just does not want to play with other kids....
She is 2 and 2 year olds often have separation anxiety to deal with which means they want to spend more and more time with you. Have you tried reading up on routines and especially bedtime routines? I have alot of previous postings here on the site about how important routines are to children. They need a constant routine to give them a sense of stability, that all is well in the world.
I would begin with her bedtime routine. Do include a body massage, reading a book and other quiet one on one activities with her.
As for screaming when she doesn't get what she wants when she wants it, as long as it does not involve being fed, or other physical needs that have to be met, IGNORE her screaming. She only continues this behavior because it works for her and she gets what she wants.
Remember as you ignore her behavior to praise her or give her notice when she does act the way you want her to.
