babyhood
The period in one's life from 2 years and younger in which you run around in public wearing only diapers.
When I was younger, in my babyhood days, I sported the Huggie all around the neighborhood!
Babyhood
The period of time before childhood, between the first day of life up until about 3-4 years old. There are three stages of life; babyhood, childhood and adulthood.
