For the Nintendo 3DS, it was recommended to set the 3D feature off for children aged six and under. Does this also apply for New Nintendo 3DS and New Nintendo 3DS XL?
Yes. As with the Nintendo 3DS and Nintendo 3DS XL, it is recommended that only children over six should use the system in 3D mode.
If children aged six and under have access to the system, parents or legal guardians should restrict the display of 3D images using the Parental Controls feature.
