Bohn's Nodules
The white bumps present on the upper gum in this infant are Bohn's nodules. The exact etiology is unknown, but they are thought to arise from remnants of the dental lamina or from heterotrophic salivary glands. Present either on the lateral aspect of the gum (as seen here) or on the periphery of the palate, these nodules are a benign finding and will disappear with time.
