User blog:EriHonjo/My sims family

Alright, this is the first sims game I've ever played and its really fun and interesting. I've really liked it so far. But I'm finding certain issues with it that are seriously making me upset, which is why I'm making this blog. I hope you all can help me and I hope this is the right place to do this.

I have The Sims 3 for the ps3. I have heard you can have up to 8 people in a household but my house will only let me have 6. I have 2 couples and they each have a kid. All of my sims are related through either blood or marriage. I have expanded the origianl house I bought in the game so now it has 8 bedrooms and 3 bathrooms. One of the bathrooms isn't finished quite yet though. I want to have one of the couples have at least 3 more kids (I know that goes over the limit) because one of my sims has the lifetime wish of being surrounded by family.

I really like having all my sims in the house and would rather they all stay. I did have the thought of moving one of the couples and their baby out but a warning keeps coming up that the sims I leave behind will be removed from the game and I don't want that. I've worked really hard with all these sims and their stories aren't done yet. :(

I've googled what to do and there are not really any answers. Obviously the only answer, at least as far as I can tell, is to have them all stay in the same house but IT WONT LET ME HAVE MORE KIDS AND THIS IS THE PROBLEM. Can any of you guys help me figure out what I'm doing wrong and how to fix it? Or can you give me some idea I obviously haven't thought of? PLEASE HELP ME!!!!!
