Answer:
I would say infancy.
Explanation:
Cause, you know, when you're that young you're considered an infant, at least until 1, then early childhood is probably toddler age, middle childhood is probably around 8 or 9 until you enter adolescence, which is when you become a teenager and become this weird mutant creature, half child, half adult.
LOL I hope this helps!
