Pretty questionable whether you should be letting a five year old use any VR headset. Oculus Quest specifies only ages 13+ and the science is definitely not settled as to how VR use would affect motor coordination development. If nothing else, the ergonomics really are not going to work for a child that young using any headset released to date (and I don't imagine any company sticking their neck out to release a targeted pre-teen headset anytime soon).
