Sims2 Mac CPS took two sims kids…. Why?

I had hired a nanny and cleaning lady for the single mom after she had a baby and now 3 (!!) kids to look after. her levels of hunger, fun and exhaustion dropped to red.. the hired people helped clean up while she rested, bathed and caught up mentally. Whole she slept CPS came in and took the 2 youngest kids! I mean.. what? They where taken care off by nanny while the cleaning lady helped organize it. Curious what to do.. I put the motherboard on the single mom’s account so she could afford them.. how do I get the kids back?
