Toddler daycare MOD

I don't know if the Sims 4 works like previous games, but the way of doing it in my opinion would be to make it like a school career (School are generally forced careers for children and teens in the game).
So you would create a "daycare career", that parents could make their toddlers join (like a new interaction with the phone).
You could create multiple ones with different hours to fit the parent's career.
They could learn something from it, have tasks, etc.

I dunno if you can make the parents "pay", with something like a negative salary to the career. If not, you would have to create a different system to make the parents pay, or make it free.

It could even be an active career, where you would follow your toddler to the daycare with tasks to do (like Go to School).

I'm not a modder, just some ideas.
