My mom wrecked my car update 2

I married Barbara and she had our son and in her last months of her pregnancy she went off sex. My mother Clare took up the slack and thinking she was passed having children didn't take precautions and told me I didn't need to either. Well, she wasn't passed having children and got pregnant and she gave a baby sister/daughter. My name is on her birth certificate as nobody took any notice of me with my wife and son and saying my father had departed. Assumed he had died, so no awkward questions and Barbara is pregnant again and Clare is taking precautions just in case. I'm very happy with my life and have finish the VW.
