My youngest child has taken to calling both his father and me, Maudy. At first it was reserved for Troy and I assumed that, what with being around me all day, every day, he was just wired to say, "Mommy." And that, halfway through, he realized he actually wanted his daddy and changed the name accordingly.
Troy would, rather ineffectively, say, "Buddy, I'm DAddy."
Then, Matthew just started calling both of us Maudy. He still refers to us as Mommy and Daddy most of the time (or Mama, Dada, Mom, or Dad) but several times a day we get the more universal moniker. The way he says it is absolutely adorable and I would so get it on video if I had a clue when it was coming.
The other day, he switched it up on us. Toddling into the room in need of assistance, he looked at me and said, "Dammy, hep me."
I'll take Maudy over Dammy any day of the week.
