Just for fun - baby size descriptions :)

Elise
This week (17), Glow is comparing the size of my baby to a white onions - but yuck! I can't stand onions. 
I prefer to think about my baby being about the size/weight of an iPhone :) (if only there were a cross between the 5s and 6 ;). 
What week are you and what "better" (non-food?) comparison do you have?
