As a parent myself, might I suggest using that as her middle name.

When we named our two boys, we chose classic yet timeless names for their first, but did have some fun with their middle names. (and NO, they are not named “Ben” and “Will”. My god, I actually know 6 families that have two boys with those names). That way, we got to name them something fun, but they had good classical first names they could go by through out their lives. Our boys were born during the height of what I call the “din” period. Where a lot of babies have names that ended with some derivation of “din”, “dyn”, “den” or something along those lines.

There is a very good reason why there is an entire subreddit on that other site called “/r/tragideigh”.
