I've found that I have to view season in term of like Game of Thrones where it's Summer for 10 years and then Fall for a few and then Winter for who knows how long.
But that's me personally, I found that if the seasons change to much I get tired of all the repeat holidays and events. And since the lowest setting for seasons are 7 days if you're going realistic ish then 28 days is technically a year,
I haven't tried playing with long lifespans yet. But maybe you could tweak the different age groups however you feel, but leave the adults as is? Cause there's really only so much toddlers can do, before they're just there to annoy you. At least children can start gaining some adult skills after maxing their skills.
