We are guilty of nick-naming our kids and using those names way more often then their real names. I am sure it is going to be a great source of confusion when they are a bit older...
Roark:
Raorkasaur
Roark-a-dork
Dork
Cole:
Coley-moley
Coley Kong
The Mole
Kong
They both get called Butt at various times during the day - as in "you are such a butt" or "god, he is being a BUTT" - but only out of love...yeah.
There is also this really stupid cheer I do with Roark - and no, I don't know why:
Your big, B-I-G
and your bad, B-A-D
and your Roark, ROAR!!!!!
