Nitrous sedation can carry some risks and should only be administered to children who are physically and developmentally able to cooperate or understand directions. Therefore, the recommended age limit for considering someone too young for nitrous sedation is <2 years old. This means children younger than 2 years old should not receive nitrous sedation due to the potential dangers and lack of cooperation or understanding. The other options are incorrect because they either do not specify a specific age limit or they suggest a younger age, which goes against the contraindications for nitrous sedation.
