Ok, so say my surname is Smith and DP's surname is Jones, this is what our DC are called:
Dc1 Smith (not biologically his but together since he was 1)
Dc2 Smith
Dc3 Jones
We're not planning on getting married in the near future or even at all, but we are planning on ttc another baby. So which surname would it have?! I wish they all had mine tbh :(
