Quoting Third Time Mommy:" That's a good idea, I'm sure he'll earn one, my SO has been calling him Deezy. I don't know how I feel about that one yet."
If you watch phineas and Ferb, my son sort of earned the nickname of Doofenshmirtz. lol Not for anyother reason than I loved hearing him say it. Now I will call him Shmirtz once in a while.
I have twin girls that are now 4. One of them we call Neekers. This is because when she was learning the next milestone she would practice it when nobody was looking. You could leave the room and peek at her getting up on her knees to try and crawl, the second she saw you, she would promptly "fall" and start to cry or something to distract you. lol She practiced talking in her bed as well. I heard her say most everything via baby monitor before she said it out in the open.
The other I call Peapie. Her sister was sweet pea when she was born because she was just so tiny and somehow we got Peapie for the other. We just call her Pie once in a while.
