I have a slew I use at random and a few special ones for each of my children; some silly and some endearing.
I call my Nathan, Nathonian or Short-Pockets and sometimes still call him by his nurse-name Mr. Moo which has graduated with him to Mr. Man. My Allie hears Allie-finale, stinker (from her Daddy), & Shortcake on the regular. My youngest, Isaiah, I currently have A LOT of pet names and nurse-names for, some I'd have to think how to spell, hahah ; Zaza, Za-mo, Bitsey....the list goes on. My husband and I are fond of petnames.
