Alright... normally I just lurk but I think I'll join in on this one.
As a previous poster said, I fear for my child when she grows up. She'll probably get in trouble in school for calling others the names we use at home!
For DH: Dorkbutt, butt-dork, cutie (most the time I use this one), CSM (short for "cutie sexy man" -- my all time favorite -- this one is also interesting when we go to Wal-mart and they page for a CSM
), and when I really want something "sweetie" said in a sing-song voice (this works like a charm, lol!)
DH for Me: Punk, Mama Punk, dork, and on cards or tags "Pretty Polar Bear", he'll also use dorkbutt but not as often as I use it for him.
He also calls me something else when I'm being "bad" but I don't think he'd like for me to share it.
For DD: DH's nickname for her is Ellie but he'll also refer to her as his 7 pound food processor, I'll call her cute-stuff or sugar-bug (though I'm trying to stop with the sugar-bug as that's what we want to use when she brushes her teeth -- she's washing the sugar-bugs away). When she was first born and we were in the hospital with her I'd call her "My Precious" like Smegol does in The Lord of the Rings. DH would just roll his eyes!
My mom calls DD bubble-butt.
Kitty #1: Sev-meister, Sir Pukes-a-lot, Sir Cries-a-lot, Little Punk (it's a wonder he answers to his name: Seven)
Kitty #2: Fudgie, Fudgie-pudgie, Fudgieway, and DH will also refer to her as "The Daughter of Satan" (her name is Fudge)
