When do we start culling Sims?

I started a new game lately and am of course using MCCC. I have as much autonomy as possible in my games. The NPCs/townies have been breeding like cockroaches. Mr Rocca has had 10 pregnancies each with a different partner and he has been abducted by aliens a few times each resulting in him becoming pregnant. He is pregnant again with a different townie. Dude stop abusing autonomous try for a baby I can't keep up lol. Raj got married to a townie and has had even more kids than Mr Rocca has. Marcus Flex married J Huntington III and they have had quintuplets. Lilith and Vlad just had triplets. Caleb got abducted by aliens and gave birth to 6 babies. The Goths and Landgraabs have had more kids. Cassandra moved out and married Wolfgang Munch. This to me is very entertaining. I am playing multiple households. My Sim Regina has gotten married to Luna Villareal while I was playing another household and they had 5 babies. Even the Sims who hate kids are having lots of kids. So on and so on. This is really entertaining since I am not used to Sims in my games having so many kids. I don't like removing autonomy either. I feel the more I give them the better. I am wondering if I should start culling households.

I don't want to be a baby culler but plum these sims are going to turn into one >:) lol.

I want to hear baby stories from everyone. What are your baby adventures? Have your townies/NPCs ever gotten out of control with having kids? Feel free to share pics.
