DS is Frederick, often known as Freddie. I like that he has a (to me) strong, serious 'long' name, but also an obvious nickname, plus other nickname choices if he wants them later. Most of the names we've picked if this bump is a girl are in a similar vein, with Penelope, Annabelle and Beatrice all being contenders.
I also really like Alice and Polly, but I'm not sure they work together quite as well- they're much shorter, and don't really have nickname potential- in fact Polly already is the nickname, technically- so I'd always be calling them by their full name. It just doesn't sound right for me.
Is that an issue? Or are pregnancy hormones driving me mad?
