When will the madness start?!

My son will be two in June and all of my “mom friends” with kids the same age are constantly complaining about how bad their kid is - tantrums, hitting, biting, not eating, running away from them, not sleeping, not listening etc etc. all of which is of course totally normal for toddlers. But my son doesn’t do any of that lol not bragging - just wondering when he’ll start?! He’s sooooo sweet, soooo good, listens, follows instructions, rarely gets upset, has never hit and would never ever ever run away from us in public or at home. Has anyone had a really good toddler until all of the sudden they didn’t?!
