No middle name?

silvia • Proud mom & wife! Baby #2 coming Feb2018!

So my husband doesn’t have a middle name. Neither does his sister but his oldest brother does. I’ve always thought this was strange and his moms explanation is they just don’t.Our first born has a middle name that he goes by. I’m due in February and we are at war weather our new baby will have a middle name or not. I think he should have one, & the hubs is dead set on no middle name. 🤨 so just needing some feedback. Do you guys think it’s odd to not have a middle name?? What are some arguments towards giving the baby a middle name?? Thanks 🙏 girls!
