I'm just genuinely curious.
My 2yo (just about 2.5) is super chill and happy. He of course has moments/tantrums but they are few and far between. Like we could easily go a couple weeks without a tantrum and if he has one it's usually Sleep related.
He's agreeable and polite and generally easy to reason with. His teachers comment on how good he is.

But I feel like if 2 is this easy maybe 3 will be hellish. And I'm curious - if you had an awesome 2yo, was 3 also easy? Or did it get harder? If it got harder, when did it start?

Obviously this is not scientific and each kid is different. But wonder if there is any trend or correlation.
