A potty is a special chair or toilet for small children to use when they need to go to the bathroom.
When talking about little kids and toilets, "potty" is a word that people often use instead of saying "toilet." It's like a nickname for a toilet just for tiny humans. You might hear parents say things like, "My baby uses the potty now," or "The toddler still needs help getting on the potty." It's also common to see kids' books and toys that are about using the potty as part of growing up.
