They are both adorable and your daughter beautiful, 2Ls! Thanks for the link about Potcakes.

I was going to say Sweet Cakes or Baby Cakes, etc. in connection with Potcake, but that's just for fun.

I have a Puerto Rican friend whose name is Abdulia, which she hates, but her nickname is Juji (jew-gee) which I've always liked. Might be too close to Nellie, though.

Have fun!
