Now I have 4 kids and I am out of Nerd nicknames. So I am polling all of you to get some suggestions. I have names for the older 2 but not the younger 2. So here is what I have and their descriptions.
NerdBug is the oldest, he is 6.
NerdPie is next and she just turned 4.
#3 is an energetic 2 year old boy.
#4 is a cute newborn girl.

I am looking for long term nicknames so if you have any suggestions please leave me a comment.
