Why behavior happens, in general

The four common reasons behavior happens, explained generally. Only your child's team can say what is going on for your child.

  1. To get attention or connection from another person, such as a look, a laugh or being picked up.
  2. To escape or avoid something: a task, a demand, a place, or a sensation that's too much.
  3. To get something: a toy, a food, an activity, or more time with something.
  4. Because it feels good, or relieves something, on its own (often called "automatic"), whether or not anyone else is around.

The idea behind this framework is simple: behavior happens for a reason, even when the reason isn't obvious. That includes the hard behavior.

Why only your child's team can say

The same behavior can happen for different reasons in different children, and for different reasons in the same child on different days. Working out what's going on for your child takes an by a qualified professional, such as a BCBA, usually through an . That means observing and recording over time, talking with your family, and sometimes testing ideas carefully.

The notes you keep in the can help with that. They describe what happened. They can't say why, and nothing on this site can.
