There are many elements in the care received that help set us up for success, but the hug and encouragement are the ones that hold the most power. When touch is nurturing (in other words, loving), kind, and wanted, touch plays a key role in healthy development and is involved in regulating emotions and stress responses. Touch has the power to heal.
I had an aunt that was born with several medical conditions and challenges. She was not able to communicate verbally, so, as you can imagine, she would get frustrated when she needed something and no one knew how to help her. Over time it became very clear that she was aware of everything, yet lacked the ability to say it. To know her was to love her. The more time you spent with her the more you understood what she needed.
