I always play big households. Right now I have 7, 6 sims and a dog. I'm a micromanager for sure, the pause button is my best friend. I don't find it hard at all, but I'm afraid my tips and tricks are just ... practice. Lots and lots of practice. I played this way throughout Sims 2 and 3, so I've had literally years of practice. It is much easier to play big families in Sims 3 and 4 than it was in Sims 2, I can tell you that! Maybe that's why it's easier for me, because I started out in Sims 2. My best advice is if playing large households isn't fun or is stressful for you, just don't do it. Play however is fun for you.
