Peter likes to be called "Peter" not "Petey" or "P" or "Pete" or any other variation of his name. He loves his name, but he allows for a few nic-names. "Mommy, it's okay if Daddy calls me 'Buddy.' It's okay if you call me 'Buddy' too."
Nic-names are interesting to him. He told me one day, "Mom, Jesus says it's okay if I call Him 'Father.' It's okay if He calls me 'son.' "
