I'm not sure how this evolved but I now put "-sies" at the end of many words when I talk to my daughter. Almost like Gollum from Lord of the Rings with his "Hobbitses" and "Bagginses". Almost. And without the creepy voice.
For example, my vocabulary now frequently includes:
and so on...
She smiles when I do it, and I'll do anything into eternity for the continuation of those gummy grins.
What words/phrases do you find yourself reverting to with children?
