My nieces and nephews have always come running into my arms for a hug, until they outgrew it, all at different ages. Now the 7 y/o is a little moose, half as big as me already, and can just about knock me over.
Besides, I think he thinks he's too old now.
Now he developed this gesture to show me how glad he is to see me.
When first greeting each other, I bend over just a little (I'm only 5'1"
) and we gently bump foreheads, then he holds up his little finger and I tap it with mine.
But once in a while he likes to surprise Aunt Serena and he's bumped my forehead so hard I saw stars!
But then sometimes he just hugs me anyway.
And I love it!
