Toddlers - do you level them to level 3 or level 5 before aging them up?

I micromanage the toddlers and they can all get to 5 within in the normal lifespan.

For me, it's however far they can get on a normal lifespan. Depending on my current storyline and the number of sims in a household, that can be anywhere from level 1 to 5.

I mostly play on Long now, so it’s plenty of time to get all level 5 skills, particularly since I have the Education Overhaul mod which helps raise skills when toddlers are at preschool. I’ve never had them get to level 5 on Normal with all of the skills, usually Movement and maybe one other. I do usually manage to get level 3, though. One thing I have noticed is that you don’t actually have to max out the Potty skill, although it is useful to get it to level 2 so they can go on their own (if they don’t have the Independent trait).

Level 5. I'm playing with a long lifespan, so there's a lot of time to get there.

Yes, but not mostly on purpose, I play on long lifespan.

I never used to bother but since growing together came out i have been making more of an effort with them. I always try to get them maxed out to level 5.
