So sorry to hear about your owl sweetpea - although props to you for having a pet owl in the first place, that's amazing! Horrible foxes 
Welcome back lutrinae, haven't spoken to you in the real world for a few days either so hope all's well.
Middle names. Interesting question. I personally feel they're a bit redundant (I wouldn't say old fashioned necessarily) but are a nice way of a) giving someone a meaningful name that you wouldn't want to use for their first name, such as a relative's name, or b) giving someone options if you've chosen a slightly wacky first name that they may wish to change later in life!
We'll be giving ours a middle name for sure and part of me hopes it's a girl so I can use my nan's name - it was Agnes which I wouldn't use as a first name but would love to honour her somehow as she was a very special person.
If it's a boy and DH has his way there's a good chance that both first and middle names will be inspired by famous actors... I won't reveal who just yet
