How to quickly gain toddler skills?

I don't know if there is a specific lot trait for toddlers to help them get skills up faster, but you should try adding in that firstly. To quickly get up the movement skill, I recommend clicking of the toddler and selecting the option for them to run around or wander, and pretty much let them explore the house/yard for a bit. The potty skill is pretty simple. Let the adult teach them for a bit, and then have the toddler go to the potty themselves after they're able to. Avoid having them use their diaper- it's just a waste of precious skill building time and is brings down hygiene. Communication is easy as well, just sit and let the parent and kid chat for a bit. Imagination can come from toys like the dollhouse, but I always read my toddler bedtime stories, and in no time I ended up accidentally maxing out that skill. I used the tablet games and the nesting blocks to max the thinking skill. I sometimes had an adult help, but only when they had free-time. Using these methods, I ended up getting the Top Notch Toddler trait.
