So, one of these is currently the front runner for our DS who is due in May. DH likes Theo but says he can’t picture ever actually calling him Theodore. I agree that in reality he’d be Theo 99% of the time but I quite like the idea of having Theodore as his full name because we love the meaning (we are religious). My main reservation is that due to family links he may well also end up having two middle names - is Theodore [name] [name] going to be a bit of a mouthful or are we overthinking it given that nobody is actually going to use all three in daily life?
