You have to name your child like this:

You had a child and you have to name them by combining your name and your partners name.

For example if your name is Olivia and your partner is Liam, the babies name can be Lia or Livia or even Oliam, depending on which one you prefer.

What will they be called?

Mine will be named Romad. That's the best I could come up with :D
