Names

So as most bloggers know you don’t use your children’s real names for privacy and safety reasons.

I am now putting it up for votes on what names to use:
Things you can think about are daddy is a mathematical person. Mommy is creative and artsy (and also very mathematically brained). 

My oldest daughter has gone by KPie (because pie is 3.14159) up until now.  I can continue using this name or I can go with…
kanga, kangaroo, kayak, kilo, kite, kitten, kiwi, koala, knowledge,

My youngest was going to go with SweetE.  I can continue with it or also use…
eagle, eclipse, egg, electricity, electron, element, elephant, energy, equation, eraser, erosion, evening, event,

OR any other suggestions for either child!!!
