Whether due to her parents' presence or infant perspective, the little girl in the stroller is far braver than most Guests at the event. Halloween Horror Nights does not have an official age rating, though even Universal believes 13 is the rule of thumb.

While there is no official rule banning infants from Universal's Halloween Horror Nights, it is strongly discouraged by the parks and the fan community. The event is designed as an "PG-13" adult horror experience, featuring high-decibel soundtracks, intense strobe lights, thick artificial fog, and "scare actors" who jump out at guests. For a baby, the extreme sensory overload can be physically harmful—especially to their developing hearing—and the startling movements of crowds in dark, congested houses pose a physical safety risk. Furthermore, the dark and crowded environment makes navigating with a stroller or carrier extremely difficult and potentially dangerous during a "scare" moment. Most importantly, the frightening imagery and constant screaming can be traumatic for young children who cannot distinguish between fantasy and reality. For the safety of the child and the enjoyment of other guests, leaving the baby with a sitter is the standard recommendation.
