Kids nicknames...mine are

[DebD4T]

DS (Christopher) is Chris, Chrissy or Junior. When he was little and very skinny we would call him Bones.
DD#1 (Danielle) is Dan, Dani, DanDan and when we make her help clean, she's Daniellarella.
DD#2 (Jessica) is Jess, Jessie, JessaFessa, or her favorite, FooFoo.

DD#1 calls DS "BeaverBoy" and DS calls DD#1 "MonkeyGirl", but only at home
