At two, they have not hit individuation. They care about what you think, they care about pleasing you. Boundaries are fluid and don’t have to be stringent. Then three hits and you think you still have the same sweet child who cares about what you think. But because of individuation, your little one doesn’t give a rat’s ass about what you think. So now those boundaries need to be strong! What gets tricky is that in many ways toddlers seem to be practically the same child at two and three, but psychologically, they are worlds apart.
