As explained in the previous two lessons: Variants you add on a parent motion component, are inherited on its children.

It is exactly this that is very helpful when animating multiple children. By default if you change the variant, they will change all at the same time on the children. Framer Motion also provides a way to change the variant of each child with a small delay.

Enter staggerChildren

staggerChildren is a special property you can add to the transition prop, whenever you are animating with variants.
