Fear is an emotion which is brought upon by an unfamiliar situation.  Own the situation and adapt quickly and fear will become an opportunity to learn.

Take swimming for example.  Today, at 2.5 years old, we took you swimming.  Though you’ve been before you were not letting go of me.  Fear took over.  I observed that you were taking in the situation, observing others and quickly adapting.  You then let go and continued to learn.  Well done!
