My children have different fathers and with that they have different last names.
DC1 has his dads last name and DC2 has mine
DC1 will be starting school next September and I was hoping to enrol him with my last name so when DC2 also starts school they will both have the same last name.
I had siblings with different last names growing up and it lead to questions from people at school and also sometimes people using the wrong last names for us.
First of all is this possible and second of all AIBU?
