Tattoo related to dad & daughter

Tattoo enthusiasts, hi.

I have no tattoos at the moment, but have always wanted one. My daughter is due in January, and not to be too cliché but I’d like a tattoo related to her - perhaps something with date / time of birth. The whole tattoo doesn’t have to be related, just an element, so I can add to it as and when. The aim being to go for a full sleeve or at least half sleeve.

Any design ideas or somewhere I can get some inspiration?
