Just thought of an episode of Miami Ink I saw recently, where a guy wanted his son's name on him. He got his son to write his name on his chest (the son was writing on his dad - that came out a bit wrong!!), and used that as the stencil. So the tattoo was in childish writing, but in his son's writing.
It was such a sweet idea.
If your daughter is old enough to write, you could do that, or if she is too young you could hold off for a few years until she can.
If she is older, and can write perfectly well, you could always do it anyway. It would be nice to have it in her writing!!
