My kid was as tall as me by the time he was 15. Now at 22 he's his Dad's height.
There are still two simple things that I can use to maintain some domance (SP) to our relationship. First and foremost I do often remind him that I "am still da Momma!" That ususally works until he turns me in by calling Grandma who, of course, is "still da Momma" for me
But the really big leverage in our relationship comes through the check book! That one not even he would jepordize. Momma ain't happy then Momma ain't writin' no checks!
