Once. When i was at the age of 8, a mother that my father had known had moved into my fathers house and was like a step mom even tho i still got to see my actual mom each end of week, her name was jacklyn and she had a kid about 4 years old when i met him named jaxon, they lived in my house for about 2 years until jacklyn moved out of the house thus i am a only child again.
