Every actor has to get their start somewhere, and Walker was no exception. Though he broke into the industry by starring in TV shows Highway to Heaven and Throb as an adolescent in the mid-to-late 1980s, his first on-screen appearance was at the tender age of two, as a baby in a Pampers commercial in 1975. Despite several vintage commercials posted on YouTube claiming to feature a young Walker in the pursuit of views, none have been confirmed to be the real deal, so you'll have to settle for this adorable picture of the actor as an infant instead.
