Iv two kids already both have my surname and im due my third soon. This one has a different dad and while we are in a relationship baby was not planned but very much loved. My partner wants me to give baby his surname but im leaning towards my name as firstly my other two have my name and secondly we have been having some issues in the relationship and unless big changes are made I can’t see us being together forever. He keeps saying all his nieces and nephews have his family’s name and our baby will be the only one different but the same argument could be made that my other kids have my name. Iv suggested double barrel surname but he’s not happy. Would just like some advise from others outside of the situation as you can expect my family are on my side and his on his side.
