Mine may be "funky" but it isn't really funny...so, sorry if this is a downer.
I had three miscarriages before being able to carry my son to term. While the babies were in my uterus we prayed for them and talked to them regularly. It seemed so impersonal to just refer to them as "the baby" so we gave them each a nickname that we would call them while they were inside of me. They'd get their real names later.
I used the first two letters from each of their names: Kipper, Zulu, and Doodle.
Kizudo,
I'm sorry about the miscarriages.

It is a very touching story and it is wonderful that you keep the babies so close to your heart.
I totally understand about not wanting to call your baby as "the baby" since the momento we kenw it was a girl we always talked about Valerie (that is my daughter's name)
I don't have a nickname or anything, but my baby gets called Bubal, PJ, and Poopy a lot. I hope none of them stick!
Now that you mentioned it, I used the wrong word

I meant your username
