ACTING CONFUSES KIDS.
IT'S easy to see why Madison may find scenes upsetting.
Babies recognise different emotions and react accordingly. Every mother knows that when they are angry, their babies either cry or they might express anger themselves. A young child feels when their mother is sad or depressed.
For a two-year-old, who understands much more, such situations can be even more traumatic. Madison has been in scenes where adults act out extremes of emotion.
At some level she feels that it is "acting" not real life, so she feels a conflict between what is the real feeling of the actor towards the other, and the feelings they express. When the cameras stop, she will be confused and upset.
