I suppose we can never outgrow hugs...Admit it: hugs warms you and nothing compares to a Hug! A hug connects two people in ways that cannot e expressed in words.
Never forget that the little ones need a hug - in fact they need it to thrive. Mom and me still hugs and before my late dad passed on, he would tell me how much he loved me with a hug. ;) Warms my heart to just think about it. Interestingly, in this article, the author calls a hug a 'behavioural secret weapon'.
