Honestly not trying to sound discouraging haha, but from about 1 1/2 until 3 1/2 was basically the toughest time with my girls. Still many beautiful moments, but having two little ones able to run in different directions who do not listen to any commands and are basically constantly on mission to find something that can injure them... It was not a fun time.. My one tip is, in hindsight I shouldn't have felt ashamed to buy these kids leashes. I thought that was not appropriate for a child and people would think of me badly, but I'm absolutely over that now. If my next one is as crazy as the first two, I'm getting a leash any day!
No magic answer but I do think.its harder because of twin escalation syndrome. Little issues become huge very quickly. I learned that my two need different things to calm them down.
