An adult baby is an individual, typically an adult, who enjoys role-playing as an infant or toddler, often for comfort, emotional release, or sexual gratification. This can involve wearing diapers, using baby toys, and engaging in activities associated with early childhood. The practice is often part of a larger community known as Age Play, which includes a variety of age-related role-playing scenarios. It's important to note that this behavior is consensual and varies widely among individuals in terms of how they express it.
