DH has a DS from previous relationship and we are due a son together next month. DS1 doesnt have his fathers surname but has his first name as his middle name e.g his own name ,John junior as middle name after my DH and then his mother's surname. My DH really wants our son to be called after him so would be John junior then this one would be having our surname. I think its unreasonable as his first son has this as his middle name already. Who is BU? Me or DH?.
