I would not recommend it. The question is can a 6 year old keep quiet and still for many hours at a time?
She was 6 years old in 1886.
You should wait at least 6 hours after naproxen if you want to take ibuprofen or any other anti-inflammatory drug... The mechanism of action is the same... you won't get any additional benefit by taking ibuprofen before that 6 hours. You'll only have more side effects.
They are usually 6 or 7.
