What can cause my 4 and a half yr old to wake up every night crying and fighting?

Other features ??: If the kid is fully awake when you check him and calms to your visit, this can arise from many sources.Separation anxiety, changes in living conditions, absence of a parent, all may play a role.A medical condition should be evident during daytime activities.If the kid is not awakeor doesn't immediately waken to your touch, it might be a sleep disorder called a night terror. See your doc for details.
