My 13 year old son still need a hug and kiss. He needs it once a while especially if there is alot of pressure in performing on something, school or sports or just alot of things happening that week.
Unfortunately, sometimes, i don't like to be huggy or kissy and push him away. But, i notice if i do it in a humorous way like he's a baby, I get a smile out of him and the hugging stops, so that's a win win. He likes hand holding too with me and his dad. Meanwhile his dad just wants to give him a handshake-really?!
