That is a really hard one to pair. It risks coming off as too cutesy in a combo. I thought I preferred it as a nn, but after doing some combos I can totally get into it on its own. She's good at baking pies and doing the quickstep.
I'd pair it with stuff like this:
Birdie Fenella
Birdie Margaret
Birdie Virginia
Birdie Agatha
Birdie Harriet
Birdie Phaedra
Birdie Roisin - aww
