This is a question that I've been mulling over for longer than I've been trying to get licensed. I had hoped that in my training class, they might have addressed practical questions like this.
Until yesterday, I had been floating three ideas:
1. My first name
2. Mama [My first name]
3. Ima [My first name]
But then inspiration struck. I have a little friend (Boy4--at least for now) who just turned 3 on Sunday. He can't quite say my name. Now, let's say my name were "Jenny" (it's not). Boy4 calls me "Munny." (If my name were "Serena" he would call me "Murena.") Which seems a great combination of "Mama" and my name. Plus, it's so adorable when Boy4 does it, but he is slowly growing out of it. (His parents, however, are slowing that process by no longer using my correct name :-) )
On the other hand, it might be strange for a kiddo to come into my home and have me kneel down to introduce myself and say "Hi, I'm Munny."
Yeah, maybe this requires more thought.
