A toddler is a young child who is learning to walk, typically between the ages of one and three years old. The name comes from the way these children move: they toddle, which means to walk with short, unsteady steps, like a penguin waddling across ice. Watch a toddler cross a room and you'll see them lurch from side to side, arms out for balance, sometimes plopping down on their bottom before getting up to try again.

Toddlers are famous for their curiosity and energy. They touch everything, ask endless questions (or say “no!” to everything), and can go from giggling to crying in seconds. Their brains are growing incredibly fast, learning language, testing boundaries, and figuring out how the world works. A toddler might insist on wearing rain boots on a sunny day or have a complete meltdown because their sandwich was cut into triangles instead of squares.

Taking care of toddlers requires patience because they want to be independent but still need constant help and supervision. They're too young to understand why they can't play with electrical outlets or eat nothing but cookies, but old enough to have strong opinions about both. Despite the challenges, this stage is when children develop their personalities and learn important skills that will serve them for life.
