Is there a limit on how many people you can have in your house? I have four people in there already the mom, dad, sister, and brother. I have been trying to get the mom pregnant but it just isn't working. I tried calling the adoption agent but it says they won't adopt a child to me because i already have four people in the house. What I'm wondering is, is there any way to have more kids or do I have to wait till the teens move out?
