A toddler is a child between the ages of one and three. The toddler years are a time of great cognitive, emotional and social development. The word is derived from to toddle, which means to walk unsteadily, like a child of this age.
Puberty has nothing to do with it. I'd say a child becomes a toddler when it starts to walk, before that it is a baby. Then child from about 3 or 4 years old (kid is slang) but that goes on to overlap with young teenagers. I'd say a 14 year old is both a child and a teenager.
